Symptoms: A router may generate the following error message and a traceback:

%BGP_MPLS-3-GEN_ERROR: BGP: MPLS outlabel changed, MPLS forw not updated, prefix not in routing table

Conditions: This symptom is observed on a Cisco router that functions in a VPN carrier supporting carrier topology and that is configured for BGP and IPv4.

Workaround: This is a cosmetic issue, the traceback is harmless and the functionality of the router is not affected.
