Re: understanding eigrp topology table

Hi, the correct answers are C, F, E you can determine this by looking at the fesible distance numbers and the word via a certain interface, in this case int e0/1. EIGRP is a great routing protocol for large network since it only changes the routing table / topology when a change ahs been made or a link has failed. I foung the cisco learning center very helpful in learing routing protocols, check out the link below. HTH

Re: understanding eigrp topology table

I will explain whats confisuing me

if you look at the link, the network 172.20.10.0/24 is directly connected to the neighbor 172.20.10.2. Now the FD for this network is given as 28160

Now we also see that 172.20.3.125/25 is learnt from 172.20.10.2 wiht a AD of 28160. If this network is a directly connected subnet, then the FD should have been 28160 (AD to reach 172.20.10.2)+28160 (AD to the network) which doesn not seem to be the case

Am i missing something here?
