Hello!
I'm trying to configure BGP Backdoor on my Nexus 5548TP switches. I have BGP peerings established, however in this case, I have a DR facility and I only want some EIGRP routes preferred over the BGP learned routes. In this case, we have a couple vendors that have VPNs to both locations. I want the primary path to always be preferred and if that disappears from routing table, use the BGP learned route. I have an eBGP session with my firewall which is advertising the routes in question, so the AD is 20, which is fine for interfaces hanging off the firewall, but the other routes i want them to have AD of 200 so my EIGRP route is preferred. I've tried using a route-map on NX-OS for this without much luck.
NX-OS v 5.2(1)N1(4)
DR-CORE1(config-route-map)# router bgp 65107
