yesterday I posted the following question:
I have a quick BGP question.
If R1 has 150.1.0.0/16 in its bgp table, is there a way to advertise this
route to ONLY ONE eBGP peer. I know you can use distribute-list to deny
and allow certain routes, but if you have 10 eBGP peers (hypothetical
situation) and you I wanted to send this route to R2 only, do I need to
specifically deny that route via an access-list (or prefix-list) all the
other nine peers? Seems like there must be an easier way.
I got back some very good results but it brought up another question. I
noticed that bgp "network" statements have a "route-map" option
and "backdoor" option. I know what "backdoor" is used for, but what kind
of information can be set with the route-map option. Can I use it to
solve the question I posted yesterday (only advertise the route to
specific bgp peers)?
