HI,
I have a very simple set up
(lo 0)R1----frame PVC-----R2(lo 0)
Configs ar shown below. I am setting up EBGP between R1 and R2, using Lo 0
as the peer IP address in both cases. I can do an extended ping from R1 to
R2 usng Lo 0 as the source address. The neighbor relationship however will
not progress beyond active.
The following is the output from debug ip bgp
03:59:52: BGP: 11.11.11.11 multihop open delayed 19344ms (no route)
There is a route, but it just happens to be the default route. It all works
fine if I put a more precise route onto R1 or R2. Why does it fail with
default routes, when extended ping works fine ?

Any advice with this strange behaviour ?
