show bgp l2vpn evpn
Use this command to display details about Layer 2 Virtual Private Network (L2VPN) Ethernet Virtual Private Network (EVPN) routes.
Note: A BGP EVPN route update received for an unreachable IP address is also listed by this command and as a best route. This is because the next hop tracking feature is not supported for the EVPN address family. However, the tunnel to this IP address is shown in unresolved state by the
show nvo vxlan tunnel output.

show bgp l2vpn evpn (((vrf WORD)|(rd WORD)|)((prefix WORD)|)(detail| time|))
show bgp l2vpn evpn mac-ip ((vrf WORD)|(rd WORD)|)
