Redistribute OSPF into ISIS

amo_messi114

Hi guys I'm having trouble redistributiong OSPF into ISIS. Using the next topology: R1---R2---R3
R1-R2 link is in ospf area 0.
R2-R3 is configured with ISIS.
I've inserted the default-information originate always and it works because R2 receives the default route but R3 is no getting. The redistribution is also working because R3 can see R1's loopbacks interfaces.

Thanks

R2 and R3 are configured as level-1-2 by default
What I don't understand is that if R3 gets ospf redistributed subnets, why dosen't it get the default route of R1 if R2 has it in its routing table as O*E2 .

Thanks

Do you have a config? Your description does not give me enough to go on.

Questions:

1. Is R2 configured as a:
   1. Integrated IS-IS L1 router
   2. Integrated IS-IS L1-L2 router
   3. Integrated IS-IS L2 router
   4. Integrated IS-IS other router
2. Is R3 configured as a:
   1. Integrated IS-IS L1 router
   2. Integrated IS-IS L1-L2 router
   3. Integrated IS-IS L2 router
   4. Integrated IS-IS other router

Which router has the default-information originate always command on it?

The always keyword makes the router advertise a default to neighbors even if there is not one in the routing table. When you redistribute only routes in the routing table are redistributed. So, I'd check the routing table on the router doing the redistribution.


Just a thought....

it is always better for other to reply quickly if you post the config . with your explanation there are more question to ask then to reply. just post the ospf and isis and redistribution config .....
