PE2#To verify BGP VPLS service status, the show mpls vpls mesh command should display the BGP VPLS session in the active state. The show mpls vpls detail output must show the Route Distinguisher (RD) and Route Targets (RTs) in the correct <4-byte ASN>:<VPLS ID> format. Additionally, the show bgp l2vpn vpls detail command should reflect accurate local and remote VE-IDs, proper RD information, and valid incoming and outgoing labels, ensuring proper signaling and label exchange between VPLS peers.
