you can do for sure, but I'd approach it with caution - your "root" route-reflectors, if you see what I mean, are going to get pretty heavily loaded if there is significant transience out there. Remember that R-Rs nedd to accept updates from all clients, and flood them out to all other neighbors (client or not). Imagine what would happen if you have a two-layer hierarchy of RRs, whereby the clients at the bottom pass on their updates to the mid-layer RRs, which in turn will pass on the updates to the top-layer RRs, which have to flood out the updates.... Another possibility would be that route flaps might become amplified - ie generate multiple withdraw/announce pairs which would propagate through the network, impacting any flap-damping that may be inplemented. What is normally done is to have a fully (iBGP - not neccesarily physical) meshed backbone, with a pair of RRs at each major location, with them feeding local RR clients from there. hth Andy ----- Original Message ----- From: "Chuck Larrieu" To: Sent: Wednesday, May 23, 2001 8:49 AM Subject: RE: could a bgp reflector also be a client?
