BGP and EIGRP help

Hi, I have router A and B running BGP (5.0.0.0). I have created GRE Tunnel between them working on EIGRP(10.3.1.0).

I have published 10.50.0.0 both in BGP and EIGRP on router A. Now I am seeing EIGRP Tunnel as primary

on Router B. Ideally it should primary as BGP AD-20. Please help.

Re: BGP and EIGRP help

Rupesh,

The issue is that you are redistributing EIGRP into BGP on router B. This causes 10.50.0.0/16 to be seen as locally originated on router B (from 0.0.0.0) and to have a weight of 32768, which is preferred over the path received from router A via BGP.

Make sure you do not redistribute EIGRP routes received from router A back to router A via BGP and vice versa.
