Re: Getting pretty close to default IPv4 route maximum for 6500/7600 routers.

Hi all,

I am wondering if maybe we should make some kind of concerted effort to remind folks about the IPv4 routing table inching closer and closer to the 512K route mark.

We are at about 94/95% right now of 512K.

For most of us, the 512K route mark is arbitrary but for a lot of folks who may still be running 6500/7600 or other routers which are by default configured to crash and burn after 512K routes; it may be a valuable public service.

Yes, a Sup720/PFC3CXL defaults to 512K IPv4 routes, and reconfiguring the FIB requires a reload. So I've been quietly expecting a somewhat serious meltdown when we hit 512K :) Jeff
