Has anyone ever got the BGP Backdoor to work? I had R1 in AS 1 with 2 ebgp
peers in AS 2. AS2 Had an ebgp peer in AS 3 (R7). R1 and R7 were directly
connected running EIGRP. R7 was advertising a route 152.1.20.16 /28 via BGP
and via EIGRP. R1 was getting both /28 routes and choosing the EBGP route
because of the better AD. I needed to make it choose the EIGRP route without
just changing the distance for the protocols. I put "Network 152.1.20.16
mask 255.255.255.240 Backdoor" under my bgp process and cleared all bgp
sessions everywhere. The eigrp route would show up at first, until the ebgp
route established its peers again then it would override the eigrp route. Am
I missing something here or is this just not working? thanks,
