Creating a management VPLS for SAP protection

About this task

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 Figure: Example configuration for protected VPLS SAP. The following tasks should be performed on both nodes providing the protected VPLS service.

Before configuring a management VPLS, first read VPLS redundancy for an introduction to the concept of management VPLS and SAP redundancy:

Procedure

Create an SDP to the peer node.
Create a management VPLS.
Define a SAP in the m-vpls on the port. Note that the port must be dot1q. The SAP corresponds to the (stacked) VLAN on the 7210 SAS-R6 and 7210 SAS-R12 in which STP is active.
Optionally modify STP parameters for load balancing (see Configuring load balancing with management VPLS).
Create an SDP in the m-vpls using the SDP defined in Step 1. Ensure that this SDP runs over a protected LSP.
Enable the management VPLS service and verify that it is operationally up.
Create a list of VLANs on the port that are to be managed by this management VPLS.
Create one or more user VPLS services with SAPs on VLANs in the range defined by Step 6.

Example: Creating a management VPLS for SAP protection

Use the following commands to create a management VPLS for SAP protection.

config>service# vpls service-id [customer customer-id] [create] [m-vpls] 
    description description-string
    sap sap-id create
    managed-vlan-list
        range vlan-range
            stp
            no shutdown

The following example shows output for a configured management VPLS.

*A:ALA-1>config>service# info
----------------------------------------------
        vpls 2000 customer 6 m-vpls create
            stp
                no shutdown
            exit
            sap 1/1/1:100 create
            exit
            sap 1/1/2:200 create
            exit
            sap 1/1/3:300 create
               managed-vlan-list
                  range 1-50
            exit
            no shutdown
        exit
