Re: GSR Route Reflector: maximum number of clients?

  Something like 40 iBGP peering sessions should be doable in most 
  circumstances.  Mileage will vary significantly as a function
  of:

                physical topology
                RR Topology
                policy (routes, dampening, etc..)
                stability
                .. and other things
 
  Adding a tertiary box such as a 7206 or some such box as a BGP
  route reflector may work fine -- but can give rise to improper
  routing information. (esp. wrt route selection)

  In general, one wants the routing information (control plane)
  to follow the forwarding path (data plane) as closely as 
  possible.

I have a GSR 12008 that is acting as a route reflector and core router. 
What is the practical maximum (from an operational standpoint) number of
clients it can support? (My Cisco sources  tell me that the maximum
technically possible is large and does not significantly impact the
operation the forwarding of the GSR.)

In terms of manageability and simplicity, is it more favourable to have a
separate box (e.g. 7206 VXR) handle the route reflector job?

Thanks in advance for your thoughts.
