RE:Getting pretty close to default IPv4 route maximum for 6500/7600 routers.
And since those puppies are going to need a reload after adjustment make sure your not exposed to the component decay issue for cards manufactured between 2005-2010 or you could have a interesting night. We've hit that issue on three different 7600 chassis.

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. Even if you don't have this scenario in your network today; chances are you connect to someone who connects to someone who connects to someone (etc...) that does. In case anyone wants to check on a 6500, you can run: show platform hardware capacity pfc and then look under L3 Forwarding Resources. Just something to think about before it becomes a story the community talks about for the next decade. -Drew
