Description (partial)

On a 6500 connected directly over POS interface to a router, directly connected ping fails if on POS interfaces we have "mpls ip" configured. After troubleshooting we found a workaround which is to configured "no peer neighbor-route" command on POS interface on both routers and do a shut/no shut to the interface.

Issue started after IOS were upgraded from 12.2.33SXH4 to 12.2.33SXJ5.
