I've been having a really bizarre problem off and on the last week or two. Occasionally some of my ARCs will suddenly stop doing OSPF right. The routing table loses all OSPF routes, and the ARC stops announcing its routes via OSPF to our Ciscos. Disabling/enabling OSPF doesn't help, but most of the time (not all the time) rebooting the ARC will.
One thing that seemed to trigger it was rebooting some of our Ciscos... and since that happens so infrequently (not rebooted since going to ARC 4.2 in fact) it's hard to track down. I don't know which one exactly, maybe our AS border router dying is what threw it off.
. . .
Has anyone seen anything like this before or know of any particular settings that I might want to check? This is driving me nuts (not to mention my customers) and I'm not sure where to start.
Make sure your tc's aren't becoming the DR. To check, do a "list ospf nei", see if any of them are in any state other than "two way". To fix, do a "set ospf interface THE_OSPF_INTERFACE router_priority 0" on each of them and reboot. -- Aaron Nabil - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
