Brian and Scott,
I think the main confusion I am having is the neighbor statement in BGP.
R1 (bgp)--------R2 (Non bgp)-------R3(BGP)
tunnel====================tunnel
The Tunnel config on R1 would look something like this:
R1
tunnel 1
ip unnumbered eth 0/1 (R2 facing interface)
tunnel source 192.168.1.1 (R2 facing interface) tunnel destination
172.168.1.1 (R2 facing interface on R3)
R3
tunnel 1
ip unnumbered eth 0/1 (R2 facing interface)
tunnel source 172.168.1.1 (R2 facing interface) tunnel destination
192.168.1.1 (R2 facing interface on R1)
There is ospf runing on R1, R2 and R3. R1 can reach R3 and vice verse. The
tunnel comes up and I can send traffic from R1 to a loop interface on R3
using static routes.
I am messing up on the BGP configuration. If I use the e0/1 interfaces on
R1 and R3 as the neighbor statements, it will use the route learned through
ospf instead of the tunnels to form the adjacency. Am I using the correct
interfaces for neighbors and tunnels? If so, How do I force the neighbor
adjacency to form through tunnels?
