Configuring Switching Between Pseudowires Using VPLS Mesh Groups

To configure switching between Layer 2 circuit pseudowires using VPLS mesh groups, you can do either of the following:

Configure a mesh group for each Layer 2 circuit pseudowire terminating at a VPLS routing instance. You can configure a maximum of 16 mesh groups on MX-series routers and a maximum of 256 mesh groups for M-series and T-series routers.
Configure a single mesh group, terminate all the Layer 2 circuit pseudowires into it, and enable local switching between the pseudowires by including the local-switching statement at the [edit routing-instances routing-instance-name protocols vpls mesh-group mesh-group-name] hierarchy level. By default, you cannot configure local switching for mesh groups (except for the CE mesh group) because all of the VPLS PE routers must be configured in a full mesh. However, local switching is useful if you are terminating Layer 2 circuit pseudowires in a mesh group configured for an LDP signaled VPLS routing instance.

Note: Do not include the local-switching statement on PE routers configured in a full mesh VPLS network.

To terminate multiple pseudowires at a single VPLS mesh group, include the local-switching statement:




local-switching;

You can include this statement at the following hierarchy levels:

[edit routing-instances routing-instance-name protocols vpls mesh-group mesh-group-name]
[edit logical-systems logical-system-name routing-instances routing-instance-name protocols vpls mesh-group mesh-group-name]
