[c-nsp] Filtering /24s

[Church, Chuck]

If you're just starting to max out the 128 mb RAM on an RSP2, an upgrade
to RSP4 w/ 256mb should give you a bunch of breathing room.  You can
find them on Ebay for under $300.  50% more forwarding performance is
always a nice bonus too...

Subject: [c-nsp] Filtering /24s

Hello,
	We are looking at some strategies to reduce the load on our core

routers by filtering all routes that are /24 or smaller. The number of
/24 
routes that have propogated in the recent couple of years seems enormous

to me, and we are starting to hit the limits of the RSP-2 cards in our 
7500s. Short of chucking the Cisco gear and replacing w/ something that 
can handle a larger table, it seems reasonable to me that we could 
probably reduce the total number of routes significantly if we just 
dropped all the /24s on the floor and let our upstreams handle the
routing 
for us.

Am I nuts?
