[c-nsp] Filtering /24s

[Church, Chuck]

My bad.  I thought your original email said RSP-2.  Anyway, what IOS are
you running?  From what I've seen, the 12.0S versions are a little
lighter on memory than the 12.2S ones.  Filtering the longer routes like
you mentioned will certainly help too.  I suppose if you really wanted
to, you could grab an output of all the /24 and longer routes, throw
them in a spreadsheet, and look for similarities in the next hop.  A few
well thought out floating static routes might get more of the traffic
headed in the right direction than just a default.  Of course, keep the
defaults as well.

We're running 2 7507s in HSRP w/ Dual RSP-4/256s in them already!!!!!
But 
thanks for the advice.

Someone needs to build a replacement RSP and IOS based on a Dual-Core 
Opteron platform that is slot and card compatible w/ the 7500! ;)
