It includes information such as the neighbor&#8217;s IP address, hold time, uptime, interface, and other protocol-specific details. This table is created when EIGRP routers successfully exchange Hello packets and establish a relationship. Administrators commonly use the show ip eigrp neighbors command to examine this information. The topology table serves a different purpose by storing route and path information, while the routing table contains routes selected for forwarding. If an expected EIGRP neighbor does not appear, connectivity and EIGRP configuration should be checked.<\/span><\/p>\n<h3><b>Question 242<\/b><\/h3>\n<p><b>Which BGP attribute is used to identify the originating router for a BGP speaker?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Router ID<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">MED<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Local Preference<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AS Path<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The BGP Router ID uniquely identifies a BGP speaker within the BGP process. It is represented as a 32-bit value and is commonly displayed in dotted-decimal format. Cisco routers can derive the Router ID from configured settings or router interface addresses according to the platform&#8217;s selection rules. The Router ID is important for establishing and maintaining BGP sessions and identifying the BGP speaker in protocol messages. It should not be confused with the AS Path, which records autonomous systems traversed by a route. Similarly, Local Preference and MED are path attributes used in route selection rather than identifying the BGP speaker itself.<\/span><\/p>\n<h3><b>Question 243<\/b><\/h3>\n<p><b>Which OSPF LSA type represents a network segment on a multiaccess network?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Type 4<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Type 2<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Type 5<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Type 3<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A Type 2 Network LSA represents a multiaccess network segment and is generated by the Designated Router. It identifies the routers attached to the shared network and provides information about the segment within the OSPF link-state database. This mechanism allows OSPF to represent a multiaccess network efficiently without requiring every router to form a full adjacency with every other router. Type 1 LSAs describe individual routers, Type 3 LSAs advertise networks between areas, and Type 4 LSAs provide reachability information for ASBRs. Type 5 LSAs describe external routes. Type 2 LSAs are therefore closely associated with DR operation on broadcast networks.<\/span><\/p>\n<h3><b>Question 244<\/b><\/h3>\n<p><b>Which EIGRP packet is responsible for discovering neighbors and maintaining EIGRP adjacencies?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Query<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Update<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Hello<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reply<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">EIGRP Hello packets are used to discover neighboring routers and maintain EIGRP neighbor relationships. They are periodically transmitted through EIGRP-enabled interfaces and contain information that allows routers to identify and communicate with one another. Once neighbors exchange compatible Hello information, an EIGRP adjacency can be established. Hello packets do not normally carry routing updates; their primary purpose is neighbor discovery and maintenance. Update packets advertise routing information, Query packets request alternate-path information, and Reply packets answer Queries. When troubleshooting an EIGRP adjacency problem, administrators should verify that Hello packets are being exchanged and that relevant parameters such as the autonomous-system number and K-values are compatible.<\/span><\/p>\n<h3><b>Question 245<\/b><\/h3>\n<p><b>Which BGP attribute is generally preferred when it has a higher numerical value?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">MED<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AS Path length<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Local Preference<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Origin<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Local Preference is generally preferred when it has a higher numerical value. It is an internal BGP attribute used to influence the preferred exit point for outbound traffic from an autonomous system. Because Local Preference is distributed through iBGP, multiple internal routers can follow the same policy. For example, a network can assign a Local Preference of 200 to routes received through a primary provider and 100 to routes from a secondary provider. Cisco&#8217;s Weight attribute is evaluated before Local Preference, so Weight can affect the decision locally. Local Preference should therefore be considered within the complete BGP best-path process rather than as the first decision criterion.<\/span><\/p>\n<h3><b>Question 246<\/b><\/h3>\n<p><b>Which OSPF neighbor state indicates that routers have exchanged Hello information and established bidirectional communication?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Init<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Full<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">2-Way<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Exchange<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The OSPF 2-Way state indicates that bidirectional communication has been established between two neighboring routers. A router reaches this state after receiving a Hello packet that lists its own Router ID as a neighbor. On broadcast networks, routers that are neither the DR nor BDR commonly remain in the 2-Way state with one another rather than forming Full adjacencies. They normally establish Full relationships with the DR and BDR. On point-to-point links, the adjacency generally continues toward Full. If an expected neighbor remains in Init, bidirectional communication has not yet been confirmed and troubleshooting should focus on Hello packet exchange and connectivity.<\/span><\/p>\n<h3><b>Question 247<\/b><\/h3>\n<p><b>Which EIGRP value represents the metric reported by a neighbor for reaching a destination?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Feasible Distance<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reported Distance<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Administrative Distance<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Composite Distance<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Reported Distance is the EIGRP metric that a neighboring router reports for reaching a particular destination. The local router uses this value when evaluating whether an alternate route satisfies the feasibility condition. The local Feasible Distance represents the best known metric from the local router to the destination. For an alternate path to qualify as a feasible successor, its Reported Distance must be less than the local Feasible Distance. Administrative Distance is a separate concept used to compare routes from different routing sources. Understanding Reported Distance is especially useful when interpreting the output of show ip eigrp topology and troubleshooting alternate-path selection.<\/span><\/p>\n<h3><b>Question 248<\/b><\/h3>\n<p><b>Which BGP command displays the BGP routing table and path attributes for learned routes?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">show ip bgp<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">show ip bgp summary<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">show ip bgp neighbors<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">show ip route bgp<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The show ip bgp command displays the local BGP routing table, including learned prefixes, next-hop information, path attributes, and the route selected as best. It is useful for analyzing how BGP evaluates multiple paths toward a destination. The command can also be used with a specific network to examine detailed information about a particular route. The show ip bgp summary command provides a concise view of BGP peers and session status, while show ip bgp neighbors gives detailed information about a specific peer. The show ip route bgp command instead displays BGP routes that have actually been installed in the IP routing table.<\/span><\/p>\n<h3><b>Question 249<\/b><\/h3>\n<p><b>Which OSPF LSA type identifies the location of an ASBR located in another area?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Type 2<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Type 3<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Type 4<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Type 5<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A Type 4 OSPF LSA, called an ASBR Summary LSA, provides information about how to reach an ASBR located in another area. This information is needed when routers need to reach external routes advertised by that ASBR. The Type 5 LSA carries the external route itself, while the Type 4 LSA provides the inter-area path toward the ASBR. Type 3 LSAs advertise inter-area networks, and Type 2 LSAs represent multiaccess network segments. Type 4 information is particularly important in multi-area OSPF designs where the ASBR and the routers that need to reach its external routes are located in different areas.<\/span><\/p>\n<h3><b>Question 250<\/b><\/h3>\n<p><b>Which EIGRP mechanism is responsible for maintaining loop-free topology information and calculating successors?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">SPF<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">DUAL<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">BGP decision process<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">LSA flooding<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">EIGRP uses the Diffusing Update Algorithm, or DUAL, to calculate loop-free paths and select successors and feasible successors. DUAL uses information stored in the EIGRP topology table, including Feasible Distance and Reported Distance, to determine valid paths. When a successor fails, DUAL can immediately use a feasible successor if one exists. If no feasible successor is available, EIGRP can query neighboring routers to find an alternative path. This design supports efficient convergence while maintaining loop-free routing. OSPF uses the SPF algorithm instead, while BGP uses its own path-selection process. DUAL is therefore a core component of EIGRP route computation.<\/span><\/p>\n<h3><b>Question 251<\/b><\/h3>\n<p><b>Which BGP attribute is typically used to influence inbound traffic by making a route less attractive through AS-path prepending?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Local Preference<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Weight<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AS Path<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Origin<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">AS Path can be manipulated through AS-path prepending to influence how external networks select routes toward an autonomous system. By adding the local AS number multiple times to an advertisement, the resulting AS Path appears longer to receiving routers. If competing routes have otherwise similar or less-preferred attributes, a receiving network may choose a path with a shorter AS Path instead. This technique is primarily used to influence inbound traffic. It does not guarantee the resulting traffic path because the remote autonomous system controls its own BGP policies. AS-path prepending should therefore be considered a policy tool that influences external path selection rather than a mechanism that directly controls remote routing decisions.<\/span><\/p>\n<h3><b>Question 252<\/b><\/h3>\n<p><b>Which OSPF command provides information about the OSPF link-state database?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">show ip ospf database<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">show ip ospf neighbor<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">show ip ospf<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">show ip route ospf<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The show ip ospf database command displays the contents of the OSPF link-state database. It can provide information about different LSA types, including Router, Network, Summary, ASBR Summary, and AS External LSAs. This command is useful when investigating whether expected topology information has been received and installed in the LSDB. The show ip ospf neighbor command focuses on neighbor relationships, while show ip route ospf displays routes selected for installation in the routing table. Comparing the LSDB with the routing table can help identify whether a missing route results from incomplete LSA information or from another part of the OSPF route-calculation process.<\/span><\/p>\n<h3><b>Question 253<\/b><\/h3>\n<p><b>Which EIGRP route type has an administrative distance of 170 by default?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Internal EIGRP<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">External EIGRP<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Static EIGRP<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Summary EIGRP<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">External EIGRP routes have a default administrative distance of 170. These routes originate outside the EIGRP routing domain and enter EIGRP through redistribution. Internal EIGRP routes have a lower default administrative distance of 90. Administrative distance allows a Cisco router to compare routing information received from different routing protocols and sources. When multiple sources provide routes to the same destination, the route source with the lower administrative distance is generally preferred. Understanding the distinction between internal and external EIGRP routes is important in networks that use redistribution because an external route may lose to another routing source with a lower administrative distance.<\/span><\/p>\n<h3><b>Question 254<\/b><\/h3>\n<p><b>Which BGP message is responsible for advertising new prefixes and withdrawing unreachable prefixes?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Keepalive<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Open<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Update<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Notification<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">BGP Update messages carry routing information between BGP peers. An Update can advertise new reachable prefixes along with their associated path attributes. It can also withdraw prefixes that are no longer reachable or should no longer be advertised. BGP generally uses incremental updates rather than periodically sending a complete routing table. This helps reduce unnecessary routing traffic and allows changes to be propagated efficiently. Open messages establish the BGP session, Keepalive messages maintain the session, and Notification messages report serious protocol errors. Understanding Update messages is essential when troubleshooting route advertisements, withdrawals, path attributes, and changes in the BGP routing table.<\/span><\/p>\n<h3><b>Question 255<\/b><\/h3>\n<p><b>Which OSPF area type permits external route redistribution while using Type 7 LSAs?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Totally stubby area<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">NSSA<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Standard stub area<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Backbone area<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A Not-So-Stubby Area, or NSSA, allows external routes to be redistributed into the area while retaining restrictions on external Type 5 LSAs entering from outside. An ASBR inside the NSSA advertises redistributed external routes using Type 7 LSAs. An ABR can translate appropriate Type 7 information into Type 5 LSAs for advertisement into other OSPF areas. Standard stub areas do not permit external route advertisements in the same way, while totally stubby areas impose additional restrictions on inter-area information. NSSA is therefore useful when a branch or remote area needs limited external redistribution without becoming a fully normal OSPF area.<\/span><\/p>\n<h3><b>Question 256<\/b><\/h3>\n<p><b>Which EIGRP feature allows a router to advertise a summarized route instead of multiple individual routes?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Variance<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Route summarization<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Stub routing<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Split horizon<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">EIGRP route summarization allows a router to advertise a broader summary prefix instead of multiple more-specific routes. Summarization can reduce the size of routing tables, decrease routing update information, and limit the scope of topology changes. EIGRP supports manual route summarization on interfaces, allowing administrators to define the summary prefix that should be advertised. Summarization can also help reduce EIGRP Query propagation by creating routing boundaries. However, administrators should carefully select summary ranges to avoid unintended black holes or incorrect traffic forwarding. Variance handles unequal-cost load balancing, while stub routing limits a router&#8217;s advertised route types and query participation.<\/span><\/p>\n<h3><b>Question 257<\/b><\/h3>\n<p><b>Which BGP attribute is normally preferred when comparing two paths and one has a shorter AS Path, assuming higher-priority attributes are equal?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AS Path<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">MED<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Origin<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Next Hop<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">AS Path is normally preferred when one candidate route contains fewer autonomous system hops, provided that higher-priority BGP attributes are equal. A shorter AS Path is generally considered more attractive because it represents fewer autonomous-system transitions. However, Cisco&#8217;s BGP best-path process evaluates several attributes before AS Path, including Weight and Local Preference. Therefore, a route with a shorter AS Path can still lose to another route with a higher Weight or Local Preference. AS Path also serves an important loop-prevention function because a router normally rejects routes containing its own autonomous system number. These two roles make AS Path a fundamental BGP attribute.<\/span><\/p>\n<h3><b>Question 258<\/b><\/h3>\n<p><b>Which OSPF protocol uses IP protocol number 89 for communication between routers?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">EIGRP<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">BGP<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">OSPF<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">RIP<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">OSPF operates directly over IP using protocol number 89. Unlike BGP, which uses TCP port 179, OSPF does not use TCP or UDP transport. OSPF routers exchange Hello packets, Database Description packets, Link-State Requests, Link-State Updates, and acknowledgments directly using IP protocol 89. This is important when configuring firewalls, access control lists, or security policies that must permit OSPF traffic. If protocol 89 traffic is blocked between routers, OSPF neighbor relationships may fail to form or existing adjacencies may be lost. Verifying protocol filtering is therefore an important troubleshooting step when OSPF connectivity problems occur.<\/span><\/p>\n<h3><b>Question 259<\/b><\/h3>\n<p><b>Which EIGRP concept identifies an alternate path that satisfies the feasibility condition?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Successor<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Feasible successor<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reported Distance<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Feasible Distance<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A feasible successor is an alternate EIGRP path that satisfies the feasibility condition. The neighbor&#8217;s Reported Distance must be less than the local router&#8217;s Feasible Distance for the destination. This condition allows EIGRP to determine that the alternate path is loop-free. A router can maintain feasible successors in its topology table even though they are not currently installed as the primary route. If the successor becomes unavailable, a feasible successor can be promoted quickly, often without sending Queries to other neighbors. This mechanism contributes significantly to EIGRP&#8217;s fast convergence and provides an efficient way to maintain backup routing information.<\/span><\/p>\n<h3><b>Question 260<\/b><\/h3>\n<p><b>Which BGP attribute is generally preferred when its Origin value is IGP rather than Incomplete?<\/b><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Origin<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">MED<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Weight<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Local Preference<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1<\/b><\/p>\n<h3><b>Explanation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The BGP Origin attribute indicates how a route was introduced into BGP. When the Origin attribute is compared, IGP is generally preferred over EGP, and EGP is preferred over Incomplete. Routes introduced through a BGP network statement commonly receive an IGP Origin, while routes redistributed into BGP commonly receive an Incomplete Origin. Origin is not the first factor considered in the BGP best-path process. Attributes such as Weight and Local Preference are evaluated earlier on Cisco platforms. Therefore, an IGP Origin does not automatically make a route the best path if another route has a more preferred higher-order attribute.<\/span><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>View Full Cisco CCNP 300-415 Exam Dumps and Practice Test Dumps. &nbsp; Question 241 Which EIGRP table contains the IP addresses and hold timers of neighboring routers?
