isis redistribute to ospf problem

[zoushan]

Hello,

I configure isis and ospf redistribute like this:

R1---12net---R2----23net----R3

ISIS L2 OSPF

When I redistribute ISIS into OSPF on R2 , I see any other ISIS routes behind R1 but I don't see the 12 network which is connecting the two of them. I have seen this on both Frame Relay and Ethernet, I have used a redistributed connected matching a route-map to get the network into the table but is there any other way?

Take a look through the following link on setting up IS-IS for more information on configuring redistribution.

If you have a network statement in your ospf config for the 12 network this network will be preferred over ISIS since the AD of ospf is 110 and ISIS is 115.
