BGP to EIGRP Failover

[trob]

I have a problem with a simple topology. WAN remote prefixes are learned through BGP from MPLS provider and through EIGRP over VTI through the Internet that acts as a back up for MPLS. The router normally chooses BGP routes for lower admin distance which is wanted behavior. Problem: When WAN prefixes disapear from BGP due to remote circuit down, EIGRP routes are used as they should, but when routes return in BGP routes do not move back to BGP. Clearing the routes will return forwarding to BGP learned routes. Obviously we need this to happen without manual intervention. It's like there's no trigger for the router to go back to the BGP routes....thoughts on how I might fix this?.........Thanks

Hi

It is very strange behaviour, router should always choose routes with lowest admin distance.

Could you post outputs from theese commands when this strange behaviour happens?

sh ip route

sh ip bgp

sh ip bgp rib-failure

Hi,

aren't you redistributing EIGRP to BGP on that router?

If yes, you might need to set weight to 0 for the redistributed prefixes.

HTH,
