ospf limits...

[Ravi Malhotra <rmalhotra at BANKOFNY.COM>]

I am in the midst of redesigning an OSPF network to accommodate
significant growth, especially in the Area 0 backbone. There has been
some concern about the size of the OSPF topology that would result and
whether the routing protocol would remain robust, able to handle the odd
flapping link or memory leak. The network in question is using high-end
routers with high speed links (at least DS-3).

Are there any heuristics that someone has which may give us an idea of
the comfort zone in terms of the database size, number of neighbors,
routers, etc?

Or, could someone share information on the size of large OSPF
implementations that they are aware of?

I know that this issue is rather vague (clouded in too many unknowns)
and may only result in rather ambiguous
answers, but, one never knows.

Thanks,

Ravi
