The following examples show the output of the
show mpls l2transport vc command during normal operation and when a Label Distribution Protocol (LDP) session is recovering from a disruption.
The following example shows the status of the virtual circuit (VC) on PE1 with Any Transport over Multiprotocol Label Switching
Graceful Restart (AToM GR) during normal operation:
Device# show mpls l2transport vc
Local intf Local circuit Dest address VC ID Status
------------- -------------------- --------------- ---------- ----------
Fa2/1/1.2 Eth VLAN 2 10.2.2.2 1002 UP
The following example shows the status of the VC on PE1 with AToM GR while the VC is recovering from an LDP session disruption.
The forwarding state for the circuit remains as it was before the disruption.
Device# show mpls l2transport vc
Local intf Local circuit Dest address VC ID Status
------------- -------------------- --------------- ---------- ----------
Fa2/1/1.2 Eth VLAN 2 10.2.2.2 1002 RECOVERING
The following example shows the status of the VC on PE1 with AToM GR after the LDP session disruption was cleared. The AToM
label bindings were advertised within the allotted time and the status returned to UP.
Device# show mpls l2transport vc
Local intf Local circuit Dest address VC ID Status
------------- -------------------- --------------- ---------- ----------
Fa2/1/1.2 Eth VLAN 2 10.2.2.2 1002 UP
