Configuring a backup link for H-VPLS access
Network requirements
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 12 and to NPE 2 through VLAN-interface 13.
NPE 1 is connected to NPE 3 through VLAN-interface 15. NPE 2 is connected to NPE 3 through
VLAN-interface 16.
Configure the VPLS instance to support H-VPLS.

Configuration procedure
1.
Configure the IGP protocol on the MPLS backbone, which is OSPF in this example. (Details not
shown)
2.
Configure UPE.
