Topology table

Topology table

This is everything that I'm learning from my neighbors. Below is the topology table of R1.

There are two ways to check the topology table.

The first one show the successor and feasible successor, the second on shows all the available path

1 - show ip eig topology. 

As we can see in the output, only successor is displayed, despite the fact that we have redundant path.

2 - show ip eig topology all-link.

The below output show also the paths that are available but, not FS.
