Creating a Management VPLS for SAP Protection

This section provides a brief overview of the tasks that must be performed to configure a
management VPLS for SAP protection and provides the CLI commands, see
below should be performed on both 7750 SR nodes providing the protected VPLS service.
Before configuring a management VPLS, first read
introduction to the concept of management VPLS and SAP redundancy.
1. Create an SDP to the peer node.
2. Create a management VPLS.
3. Define a SAP in the m-vpls on the port towards the MTU. Note that the port must be dot1q or
qinq tagged. The SAP corresponds to the (stacked) VLAN on the MTU in which STP is
active.
Optionally modify STP parameters for load balancing (see
Management VPLS on page
4. Create a mesh SDP in the m-vpls using the SDP defined in step 1. Ensure that this mesh SDP
runs over a protected LSP (see note below).
5. Enable the management VPLS service and verify that it is operationally up.
6. Create a list of VLANs on the port that are to be managed by this management VPLS.
7. Create one or more user VPLS services with SAPs on VLANs in the range defined by Step 6.
Note: The mesh SDP should be protected by e.g., a backup LSP or Fast Reroute. If the mesh SDP
were to go down, STP on both nodes would go to "forwarding" state and a loop would occur.
