How to see if ospf has a redudant path

Like eigrp where we can see the topology, when using ospf is it possible I can see which backup link it will take?

Hello Carl,

OSPF has no backup route concept, the SPF calculation choices the best path for each IP prefix and that route is proposed to the routing table manager process.

Load balancing over equal cost multi path is supported.

The show ip route a.b.c.d is the easier way to check if multiple paths exist for a prefix.

Hope to help
