Routing TCP[s]IP (Vol. 11998)

The routing configuration for router A in Figure 13.20 is:

routerrip redistributeigrp1metric3 passive-interfaceEthernet0 passive-interfaceEthernet1 network172.16.0.0 ! routerigrp1 redistributeripmetric10000100025511500 passive-interfaceEthernet2 passive-interfaceEthernet3 network172.16.0.0

Configure a route filter at A that will prevent subnet 172.16.12.0/24 from being known by any router other than E.

Configure a route filter at A in Figure 13.20 that will prevent D from learning about subnet 172.16.10.0/24.

Configure a route filter at A in Figure 13.20 that will allow only subnets 172.16.2.0/24, 172.16.8.0/24, and 172.16.9.0/24 to be advertised into the RIP domain.

Configure a route filter at A in Figure 13.20 that will prevent B from learning about any of the subnets in the RIP domain.

Table 13.1 shows the interface addresses for all routers in Figure 13.21. Routers A and B are running EIGRP, and routers E and F are running IS-IS. C and D are redistributing. Configure distance commands for C and D that will prevent loops and route feedback but will still allow redundant paths.

Table 13.1. The interface addresses of the routers in Figure 13.21.

Using the distance command, configure router D in Figure 13.21 to accept EIGRP routes only from router A. If the link to A fails, D should not accept routes from router B, although D should still advertise routes to B.

Remove the configuration added to D in Configuration Exercise 6. Configure router C in Figure 13.21 to route to all destinations, including the networks and subnets of the IS-IS domain, via router A. C should route through E and F only if the link to A fails.
