First of all, thanks to whoever suggested the keepalive fix for someone else.
I have a pair 7513 routers connected to a pair 2924M switches with 2922 100BaseFX fibre connections. I have set them up as a fastetherchannel pair and run ISL on top of that. Then I got HSRP on top of the trunks with another router. One router talks to each switch.
I used to get lots of received CRC errors on the switches on both ports that listen to the router (every 10 seconds). Turning keepalives off the routers 100BaseFX interfaces almost fixed it. I now get a CRC error every 60 seconds.
So its not keepalives, but it has to be something else like that, what could it be that has a 60 second interval and messes up fasttherchannel?
I get no CRC errors anywhere else, including another fastethernet channel that links the two routers, and the interface on the routers that listen to the switches so its not length problems. The length of the fibres is about 100/200 meters between the router and switch and 300 meters between routers.
router1 -- 200m -- switch1|switch2 -- 100m -- router2
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
