In the speficic: The VC identifiers at each end must match, so that the connection is uniquely addressed and MTU settings for the interfaces would have the same In mpls the topmost label is the transport label for the other end's 1321P address and the second label identifies the remote AC Your error usually mean you receveid bpdu tagged with vlan id that does't match vlan id where bpdu was receveid In the meantime make sure native vlan is consistent on both ends of a 802.1Q trunk and your vtp switches setup like VTP mode and domain names I hope it help you.
