Multiple choice

Refer to the exhibit. All routers are running RIP version 2. JAX is configured to just advertise the 10.0.0.0/24 network. CHI is configured to advertise the 172.16.0.0/16 network. A network administrator enters the commands shown in the exhibit. What changes will occur in this network?

  1. The JAX router will ignore updates for the 172.16.0.0/16 network due to split horizon issues.

  2. The CHI router will install a route to the 192.168.0.0/16 network in its routing table.

  3. The routing table for CHI will have the 192.168.0.0/16 route but it will have an S next to the route.

  4. The ORL router will apply a 255.255.0.0 subnet mask to all networks in the routing updates it forwards.

B Correct answer
Explanation

When 'no network 172.16.0.0' is configured on JAX, it stops advertising 172.16.0.0/16 to ORL. However, CHI can still receive 172.16.0.0/16 from other sources and advertise it. When ORL receives 192.168.0.0/16 from JAX (after JAX receives it via distribute-list), ORL will advertise it to CHI. CHI will install this route in its routing table with a 'R' tag (RIP), not 'S' (static). The distribute-list controls what routes JAX advertises to ORL, but doesn't prevent ORL from advertising learned routes to CHI.
