2 routers running eigrp, during their initial startup (after neighbor discovery)What will both routers send to each other? a topology table or a routing table?If is a topology table then both routers will contain each router's feasible successor as well? Any good reference for case study?
Now that these routers are talking to each other, what are they talking about? Their topology tables, of course!
The topology table contains the information needed to build a set of distances and vectors to each reachable network, including:
-lowest bandwidth on the path to this destination as reported by the upstream neighbor
-minimum path maximum transmission unit (MTU)
-route source (external routes are marked)
As you can see, after two routers became neighbors (show ip eigrp neigh)they will start exchange information and store it on the topological database (show ip eigrp topo ) and includes all information.
The successor only for each entry from the topology table, minus entries removed for split horizon. As each route is received, the receiving router will reply with a poison reverse, which means the same route with the metric set to infinity.
The metrics are sent as components, rather than the "vector metric."
