BGP/OSPF Redistribution not able to see one remote loopback

[draftuncle]

Hi:

I am not able to see the loopback of R6 (6.6.6.6) in R1. I can see it in R2 but I dont know why it is not being redistributed into R1. There is a BGP session in between R1 and R2 and OSPF 1 in between R2 and R3 - R4.

I have the equivalent probelm in R6 with 1.1.1.1 (R1) so there should be some problem on the redistribution that I dont know.

Thanks a lot.

Hi,

This is some default behaviour of IGP and BGP.

Check below documents:

Thanks Deepak:

Ok but this is for IBGP and Im using EBGP. :)

Thanks a lot

Anyway it worked using a route-map as suggested.
