Hi all,

It was not understanding how peer groups worked after labbing things up, my 
thought process was that it did the same thing as Confederations for managing 
large Scale BGP in the sense of applying changes or adding policies to the one 
peer and things trickled down to the group...

ex...

R1
router bgp 1
neighbor PEERGROUP peer-group
neighbor PEERGROUP remote-as 1
neighbor PEERGROUP upd lo0

neighbor 200.0.0.4 peer-group PEERGROUP
neighbor 200.0.0.5 peer-group PEERGROUP
neighbor 200.0.0.6 peer-group PEERGROUP

now if I apply a filter, will it not trickle down to the rest of the group the 
same way if I'm adding this to a Confederation ?

I think he is thinking of route reflectors not peer-groups.  Although
you could use a peer-group to establish and define all the
route-reflector-clients.
