[c-nsp] realistic max full bgp peers on a sup720?

[Arie Vayner (avayner)]

Matthew,

Just to make sure that the relevant optimization has been done...
Check that you have BGP PMTU discovery enabled... What is the MSS of the
BGP sessions?
This can have a major impact on large table convergence...

Running into performance issue with a couple 6503/Sup720-3BXL routers
with about 8 or more peers.  Each peer's sending a full BGP table.

If a couple peers flap, the box typically stays at 100% long enough to
either drop more peers or drop OSPF.  

Cisco's site is vague, only mentioning 1m v4 routes.
