we use it a lot for our internal iBGP peers - if you define a peer-group
with stuff like next-hop-self, remote-as, send-community, update-source, and
the like, then all you need to do for each peer (and you can get a lot in a
fully meshed iBGP environment) is assign it to a peer-group.
Remember that Cisco recommend Route Reflectors and Confederations for more
than _100_ peers) all you need do is assign each peer to a peer group and
all those things are there already - you needn't specify it in each neighbor
statement. Saves on config lines, and keeps things standardised.
Howard,
not sure how this reduces processor loading... care to elaborate?
