How to see what ISIS routes im receiving when OSPF is preferred?

[graham smart]

How can I see what routes are being sent to me via one routing protocol when another is being prefered?

For example.

I have both OSPF and IS-IS running.

When OSPF is preffered ISIS routes dont appear in a "sh ip route isis"

I can see the OSPF ones in a normal sh ip route or a sh ip route ospf

When i change OSPF's AD to 200 so ISIS is preferred. I can see them in a sh ip route and sh ip route isis however a show ip route ospf now shows nothing.

Essentially I want to be able to see what routes im getting from both OSPF and ISIS ( even though ospf would be prefferred? )

Any ideas?

Hi Thanks,

Is there a way to show it like an ip route output?

Id like to easyily compare routing tables from OSPF to ISIS to ensure they both have the same routes..

I can see a show isis datbase verbose | inc IP is half meaningful but comparing to OSPF is tricky..

Thanks

Im trying to compare routes recieved by each protocol.

Obviously a show ip route only gives whats active in the table. So id like to be able to get a nice comparison of routs learnt but both OSPF and ISIS at a glance.

I fear this isnt going to be possible.

Hi,

AFAIK this is not possible but you can export the 2 outputs and do some regular expression  to get what you need.
