• Question 283:

  On the network shown in the figure, EBGP peer relationships are established between neighboring routers through directly connected interfaces. The router ID of each router is 10.0.X.X, and the AS number is 6500X, where X is the number of the router. Both Rl and R4 have static routes to 192.168.1.0/24, which are imported to BGP through the import- route command. R3 is configured with the peer y.y.y.y as-path-filter 1 import command for all peers. Which of the following sets of commands enables R3 to select the route with the longest AS_Path to 192.168.1.0/24?

• Question 284:

  On the network shown in the figure, IS-IS runs on R1, R2, R4, and R5, and the area ID is 49.0001. IS-IS runs on R3 and R6, and the area ID is 49.0002. The import-route isis level-2 into level-1 command is configured on R2. In AS 65000, R1,

  R3, R4, and R6 each establish iBGP peer relationships with R2 and R5. R2 and R5 are Route Reflectors (RRs), and R1, R4, R3, and R6 are clients.

  The iBGP peer relationships are established using Loopback0. The IP address of Loopback0 on each router is 10.0.X.X/32, and the router ID is 10.0.X.X, where X is the number of the router.

  R1 and R4 import the external route 192.168.1.0/24 to BGP through the import-route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import-route command.

  D. The routing table of R1 contains the route 192.168.2.0/24.
  A. The route 192.168.2.0/24 in the routing table of R4 has two next hops.
