I had heard from John Scudder (and Dave Ward actually) at some point in the near past that essentially the idea of 'peer-groups' is just syntactic sugar at this point in time. There is some attempt to keep like-peers together in update groups, but over time drift in state happens and peers are separated from the herd. In the end, this isn't super important in at least 2 bgp implementations in the field today... -chris > > Kind regards, > iLya > > -------------------------------------------------- > From: "Christopher Morrow" <christopher.mor...@gmail.com> > Sent: Thursday, November 17, 2011 9:09 AM > To: <grow-cha...@tools.ietf.org>; <grow@ietf.org>; "Martin J.
