Cisco Bug: CSCuj16186 - mpls ip command makes pings to even directly connected stops.
May 08, 2020
- Cisco Catalyst 6000 Series Switches
Known Affected Releases
Symptom: 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. Conditions: Issue started after IOS were upgraded from 12.2.33SXH4 to 12.2.33SXJ5.
