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 Figure 4-8 :
z
CE 1 and CE 2 are connected to UPE through VLANs.
z
UPE establishes a PW connection (U-PW) with NPE 1 and NPE 2 respectively, with the NPE 2
link as the backup.
z
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.
z
UPE is connected to NPE 1 through VLAN-interface 13, and is connected to NPE 2 through
VLAN-interface 12.
z
NPE 1 is connected to NPE 3 through VLAN-interface 15, and NPE 2 is connected to NPE 3
through VLAN-interface 16.
z
Configure the VPLS instance to support H-VPLS networking.
