I have a 7206vxr router with a PA-A3 ATM interface connected by optic fibre to a LS1010 ATM switch. I am getting condsiderable CRC errors on the router interface (receive side), 1000's per hour. We changed the interface on the router, it made no difference. There are about 8 PVC's on the link they are all getting CRC's in ratio with their traffic load.
Don't quote me on this because it's a very hazy recollection, but I think I recall a situation where PCR for VBR-nrt was slightly under configured by the provider, which caused some cells to be dropped. When the receiving SAR tried to reassemble the IP packet it recorded a hit against CRC for the packet. The insidious issue was this was only seen under full load when the incorrect PCR was occasionally exceeded. Again, can't say it's related to your issue but if using something like VBR, insure PCR is properly configured both on ATM routers and by the ATM provider.
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
