Hi All,
I am trying to better understand a particular BGP scenario, thought
someone might shed some light. This is probably very simple, i am just
missing the punchline. If you have 2 routers, one let's say running in AS100
the other running in AS200, and you had to EBGP peer with 128.1.1.254
unless the peers are on the same segment, you also need the neighbor
ebgp-multihop command configured on both routers.

I am confused here on what u are trying to accomplish. If your target is
to make downstream traffic of your client to enter your AS through the

Short answer. If you want all the routers in your AS to have full
knowledge of prefixes, buy some memory and extend your BGP cloud to include
them. Otherwise, follow a dynamic default and live with suboptimal
routing. Adding the third router as you suggest is a helpful
option. However, in
