Foundry and Policy Routing

Mon Aug 30 15:42:57 UTC 2004

Good Morning Everyone!

I will be asking this on other lists, but I hope to hear from you guys as
you're most likely going to have more experience, collectively, than the
other lists.

I'm trying to do policy routing on a couple of Foundry BigIron 4000
routers.  I've put sho ver info below.  I am seeing really strange failure
modes when doing this.  The main one is a random subnet or two will be
slowed down to a crawl and then finally not communicate at all.  There is
seemingly no commonality in the failures as different subnets fail and
other subnets on the same router are not affected.  There is nothing in
the logs.  There are some other less obvious failures as well.

Anyone out there in NOG-land seeing similarly strange issues on your
policy routing Foundry routers?

Thanks,
scott
