How to verify multiple paths available to a route in OSPF

[csaravanan-sym]

Hello,

How do I verify multiple paths available to a route in OSPF

I have three paths available to a route. I can see two equal cost paths shown in the routing table. The third higher metric path doesn't show up in the routing table

When I disable the two equal cost paths, the third path is visible in the routing table

Is there a command in ospf or shortest path algorithm, which can show the total number of paths available to a route and why one route is chosen over other

Thanks,

Chandru

Hi,

The third path is an unequal cost route so, you can see it in the OSPF data base and not in the routing table, because OSPF exchanges LSA and not actual routes.

Thanks for the reply Reza. Is there a way to find all paths available in the ospf database.

I just wanted to know the total number of paths available to an route in ospf area

Hi,

If you try this command

sh ip ospf flood-list

It should show you the equal cost and non-equal cost links.
