Yep. Most of the time I've seen this it's two data centers, both go TCAM
exception. You reboot DC1, when it comes back up you reboot DC2. This means
no iBGP learned routes so DC1 is fine. DC 2 is fine, until the iBGP peer
comes back and then start all over again.

Outside looking in, but we did get a maintenance notice from Shaw in
June for "Core Router reboot to resolve fully utilized IPv4 table";
let's hope for their sake they recarved TCAM while they're at it and
that they don't have too many of those hiding around the network.

Maybe related to the 512k route issue?

I've seen people reboot to recover from TCAM exception without adjusting
TCAM size only to run into the issue all over again. It's a fun way to
watch the problems roll around the network.

Hi Nanog, anyone know what's up with a nationwide (Canadian) routing issue
on Shaw?
