I have a setup as follows, and I was wondering if there was any method aside
from static routing which might work in this situation:
R4
/
R2 ----R5
\
R6
All routers are in different BGP ASs. R2 is the hub in a frame cloud. The
spokes, R4, R5 and R6 each have a single mapping to the hub, and frame inverse
arp is disabled on all interfaces. None of the routers are running a common
IGP. Now I have the individual peerings between R2 and each of the spokes, and
I thought that if I had R2 use next-hop-self and ebgp-multihop, that the
spokes would be able to see each other via R2, but without the frame mappings,
this is not happening. So I thought of advertising the networks in BGP, but in
order to do that I would have to advertise the specific host address, ie
12.1.1.4/32, and since that is not in the routing table it won't get
advertised. The only way I can think of to get around this is perhaps policy
routing or static routes, (but I'm not sure that would work either..) Am I
missing something? Still not sure why next-hop-self didn't work.. Any ideas?
Anyone??
Thanks
John
