We have a customer setup on a small MPLS network. The MPLS backbone uses bgp, and the customer uses eigrp. Whenever the customer changes or has a failure in their network, the default route that was learned via bgp drops out and doesn't come back. It is overwritten by a higher cost default route from their eigrp network.
Any ideas on how to make sure that the preferred or lowest cost route is always used?
Thanks, Brian
Your description of the problem could be more detailed. However, you may need to tweak the admin distance for the BGP route which gets redistributed into the EIGRP domain to make that particular route look prefered ........
We are having an ongoing problem with BGP to EIGRP redistribution on a particular VPN within our MPLS Network and would like a quote on technical support from your company.
The devices involved include 2x Cisco 7200 NPE-G1s acting as PE, and two Cisco 2800 Series acting as CE.
CE1 - EIGRP - announces default route PE1 - EIGRP redistributed into an VPNV4 BGP TABLE PE2 - VPNV4 BGP is redistributed into a EIGRP process to the customer CE2 - EIGRP
The route is visible in the EIGRP Database on CE1 and PE1 and in the BGP tables on PE1 and PE2.
Unfortunately, this only happens when the customer flaps the route behind CE1 (they test their failover to another MPLS network) -- when this happens, the route drops off of the EIGRP database at PE2 and therefore never makes it to CE2. To resolve the issue, a "CLEAR IP ROUTE VRF VRFNAME 0.0.0.0 0.0.0.0" command is issued and the route reappears in both the EIGRP database of PE2 and in the route tables of CE2
