SDPs are supported on all 7210 SAS platforms as described in this document, except those operating in access-uplink mode. For 7210 SAS platforms operating in access-uplink mode, management VPLS can be used for protection of QinQ uplinks. Refer to the following example for more information.
This section provides a brief overview of the tasks that must be performed to configure a management VPLS for spoke-SDP protection and provides the CLI commands, see Figure: Example configuration for protected VPLS spoke-SDP. The following tasks should be performed on all four nodes providing the protected VPLS service.
Before configuring a management VPLS, please first read Configuring a VPLS SAP for an introduction to the concept of management VPLS and spoke-SDP redundancy:
Create an SDP to the local peer node (node ALA-A2 in Figure: Example configuration for protected VPLS spoke-SDP).
Create an SDP to the remote peer node (node ALA-B1 in Figure: Example configuration for protected VPLS spoke-SDP).
Create a management VPLS.
Create a spoke-SDP in the m-vpls using the SDP defined in Step 1. Ensure that this spoke-SDP runs over a protected LSP.
Enable the management VPLS service and verify that it is operationally up.
Create a spoke-SDP in the m-vpls using the SDP defined in Step 2.
Optionally, modify STP parameters for load balancing.
Create one or more user VPLS services with spoke-SDPs on the tunnel SDP defined by Step 2.
As long as the user spoke-SDPs created in step 7 are in this same tunnel SDP with the management spoke-SDP created in step 6, the management VPLS will protect them.
Use the following syntax to create a management VPLS for spoke-SDP protection.
— config>service# sdp sdp-id mpls create
— far-end ip-address
— lsp lsp-name
— no shutdown
— vpls service-id customer customer-id [m-vpls] create
— description description-string
— spoke-sdp sdp-id:vc-id create
— stp
— no shutdown
The following is a sample VPLS configuration output.
