I am running IOS 12.2(3) on a Cisco 7206VXR and am trying to begin the steps to an MPLS core.
When I enable cef globally, however, the router periodically (no recognizable pattern) drops the protocol on all my frame serial ports on the router.
The outage period ranges from 1 minute to 13 minutes before the ports "magically" come back.
When I disable cef, all is well.
Has anyone seen this before? Can you shed light on the solution?
