Join Lazaro Diaz for an in-depth discussion in this video Configuring a feasible successor route, part of Advanced Topics in Cisco Routing: RIPv2, EIGRP, and OSPF.
- Alright, so this is what we're going to do next.…We're going to go back into our Topology Table…and let's talk a little bit more…about this Feasible Successor.…So let's type the command necessary…to get in to our Topology Table which is…sh ip eigrp topology.…Alright, and again this is a very big…Topology Table for a lab that we have.…What we're looking at is this particular network right here.…This is our focus because here…is the only Feasible Successor we have.…
Now, Feasible Successors don't happen automatically.…There's a process that they have to go through…in order to qualify to be a Feasible Successor.…Now, in order to become a Feasible Successor,…I'm going to say this nice and slow,…your advertised distance must be greater…than the current Feasible Successor distance.…It's just a little math but that's how they qualify.…So when they're doing their computations and then that…number is not greater than the current Feasible Successor…then it will not become a Feasible Successor.…
It will not be a backup route in your Topology Table.…
