Static route becomes inactive

[jonks]

We have two passports 8600 within our network running vrrp. twice a day we have a problem with 2 static routes which effects the master passport. About twice a day 2 routes both bound to a cisco next hop become inactive when looking a the static routing table on the passport. Anytraffic then destined for this network gets dropped.

To ressolve this problem i have to reboot the cisco routers and then the route becomes available again.

Does anyone know what is causing this problem and how can i try and get a fix. This has just started to occur over the last 7 days.

are you sure that the problem is on the Passports? and not on the Cisco router?

It might be. The cisco's have been in for over a year. I have checked the configs and i cant see any issues with them. What would cause the route to be inactive?

Have you turned off autonegiotiate and forced the ports? I've seen autonegiotiate do strange things when mixing vendors.

My suggestions are what I would try myself. If incorrect, I welcome corrections to my knowledge.

I have seen default routes going inactive on 8600's due to OSPF stub area LSA's from other routers (in my case Nortel, in your case possible Cisco). I never did find the EXACT reason, but changing all of our stub areas to non-stub seemed to fix the issue. Not sure if that will help at all.

Can you ping the Cisco when the static route is inactive?
