Enable bidirectional forwarding detection on each device. Answer: Option A.

EIGRP is running across the core to exchange internal routes, and each router maintains iBGP adjacency with the other routers on the network. An operator has configured static routes on the edge routers R1 and R2 for IP address 10.0.1.1, which is used as a black hole route as shown. Which configuration should the operator implement to the management router to create a route map that will redistribute tagged static routes into BGP and create a static route to blackhole traffic with tag 777 that is destined to the server at 192.168.10.100?

router(config)# route-map blackhole-trigger router(config-route-map)# match tag 777 router(config-route-map)# set ip next-hop 10.0.1.1 router(config-route-map)# set origin igp router{config-route-map)# set community no-export Refer to the exhibit.

Which command when applied to the Atlanta router reduces type 3 LSA flooding into the backbone area and summarizes the inter-area routes on the Dallas router?

Refer to the exhibit. Which command when applied to the Atlanta router reduces type 3 LSA flooding into the backbone area and summarizes the inter-area routes on the Dallas router? A. Atlanta(config-router)#area 0 range 192.168.0.0 255.255.252.0 B. Atlanta(config-router)#area 1 range 192.168.0.0 255.255.248.0 C. Atlanta(config-router)#area 0 range 192.168.0.0 255.255.248.0 D. Atlanta(config-router)#area 1 range 192.168.0.0 255.255.252.0 Answer: Option D. Explanation: … Read More »

A network operator is working to filter routes from being advertised that are covered under an aggregate announcement. The receiving router of the aggregate announcement block is still getting some of the more specific routes plus the aggregate. Which configuration change ensures that only the aggregate is announced now and in the future if other networks are to be added?

An engineer applied the configuration on R1 to prevent network 192.168.1.0/24 from being propagated outside of area 5. After the change, users have reported they are not able to access any of the application servers that were working before. While checking the routing table of the peer router, the engineer notices R1 stopped propagating any routes outside area 5. Which action must be taken to fix the problem?

A network engineer sets up a multihoming eBGP topology where multiple Autonomous Systems connect to ASN 64501. The engineer wants to block all the routes coming from ASN 64502 but allow all the others. For that purpose, the following AS Path prefix list is being used: (config)#ip as-path access-list 10 deny _64502$ What must be fixed to achieve this result?
