After completing the above configurations, you can issue the display vpls connection command on

the PEs. There should be a PW connection established and in the state of up.

Configuring a Backup Link for H-VPLS Access

Network requirements

As shown in

CE 1 and CE 2 are connected to UPE through VLANs.

UPE establishes a PW connection (U-PW) with NPE 1 and NPE 2 respectively, with the NPE 2 link

as the backup.

NPE 1 and NPE 2 each establish a PW connection (N-PW) with NPE 3. CE 3 is connected to the

network through NPE 3.

UPE is connected to NPE 1 through VLAN-interface 13, and is connected to NPE 2 through

VLAN-interface 12.

NPE 1 is connected to NPE 3 through VLAN-interface 15, and NPE 2 is connected to NPE 3

through VLAN-interface 16.
