Subject: BGP trick scenario "Not working"
Hi all,
I am trying to do a bgp scenario as follows: I have five routers in the
scenario, four are in AS1 (r6<-->r5<-->r4<-->r1) and AS2 (r2). In AS1 I
have a frame cloud with r5 as a multipoint hub and r6 and r4 as the spokes
all in one network. I also have full routes for all networks via OSPF.
I am trying to configure BGP as follows:
r6<-->r5 in one confederation 6000
r4<-->r1 in one confederation 6001
r6<-->r2 EBGP connection to AS2
r1<-->r2 EBGP connection to AS2
Problems, all the neighbors are connected except the neighbor connection
between r5<-->r4. This connection should connect the confederations. I
think the reason it won't connect is because r5 is a multipoint interface,
and the fact that all three routers r6,r5,r4 are in the same network. Is
this indeed a problem, or should this connection be working. I had thought
about tunneling this connection, or I am pretty sure point-to-point
interfaces will work, but I did want to change the underlying setup to much.
I am trying to practice confederations, meds, etc. Since r2 has two
connections into AS1. Any ideas as to why my connection between
confederations is not working. I think its due to the multipoint, but I
want to be sure.
Thanks
