Lab 11, Task 2.2, EIGRP
Hi all. I have a question abot mentioned task of lab 11, the task is asking about a method that enables the EIGRP routers (R2, R3, R5) to maintain full reachability to the network, while one of the VCs goes down. the routing part is simple by disabling EIGRP split horizon on multipoint interfaces of these routers. I mean, the routing updates are received at routers in the case of a VC failure. but with regard to the fact that, this is a multipoint network and we use same L3 network inside the FR cloud between these three routers, the encapsulation failure is occured after breaking a VC; suppose a VC between R2 and R5 is broked. so R2 will receive routing updates from R3 by the means of disabling split horizone; but decpite router R2 will send traffic to R5's IP through R3 at L3, it will not have reachablility to R5 at L2, because the VC to R5's IP address is down now and it will fail to see any map to R5. so what we can do in this situation?
