Run the display mpls l2vc brief command, and you can see that the destination address is the
peer IP address of the VC and the VC is in Up state. The following is an example:
<Quidway> display mpls l2vc brief
Total ldp vc : 2 2 up 0 down
*Client Interface : Vlanif10
VC State : up
VC ID : 100
VC Type : VLAN
Destination : 3.3.3.3
*Client Interface : Vlanif10
VC State : up
VC ID : 200
VC Type : VLAN
Destination : 2.2.2.2
5.8 Configuring the PW FRR
After the PW FRR is configured, L2VPN traffic is rapidly switched to the backup path when a
fault occurs on the master path. After the fault on the master path is rectified, the L2VPN traffic
is switched back to the master path according to the revertive switchover policy.

Applicable Environment
The PW FRR supported by the S9300 is mainly used in networking where the CEs are
asymmetrically connected to PEs.
In such networking, one CE of the VC is connected to a more reliable PE through a single link
of higher reliability. The other CE is dual-homed to the PEs of lower reliability. Two paths thus
exist between the CEs. The path with higher reliability is the master path, and the path with
lower reliability is the backup path.
The revertive switchover policy is required only in the networking where the CEs are
asymmetrically connected to PEs. By default, a delay is set for the revertive switchover.
After the PW FRR is configured, L2VPN traffic is rapidly switched to the backup path when a
fault occurs on the master path. After the fault on the master path is rectified, the L2VPN traffic
is switched back to the master path according to the revertive switchover policy.
