Using CEF on a 7500 with LANE

[Mark Turpin]

I have two 7500s in the core of an ATM/LANE network. These devices accumulate a very large number of incomplete adjacencies when CEF is enabled globally on the router.

After issuing a "debug ip cef receive", a significant portion of prefixes are being dropped due to incompletes.

From Cisco's documentation, it appears that CEF is supported on LANE. Is there a relationship between CEF and LANE that is causing all these incompletes to build up, and is there a way to eliminate the incomplete adjacencies?

Currently the router is utilizing Netflow switching, and is working perfectly.

Thanks,

I cheked around a bit, and I don't see anything specific that would be causing CEF to have a lot of incompletes on a LANE interface. I did find this:

But it seems to be related to frame circuits, not to LANE. Next step--open a TAC case, unless you can't.
