Configuring Static Pseudowires for VPLS

You can configure a VPLS domain using static pseudowires. A VPLS domain consists of a set of PE routers that act as a single virtual Ethernet bridge for the customer sites connected to these routers. By configuring static pseudowires for the VPLS domain, you do not need to configure the LDP or BGP protocols that would normally be used for signaling. However, if you configure static pseudowires, any changes to the VPLS network topology have to be managed manually.

Note:

In the VPLS documentation, the word router in terms such as PE router is used to refer to any device that provides routing functions.

Static pseudowires require that you configure a set of in and out labels for each pseudowire configured for the VPLS domain. You still need to configure a VPLS identifier and neighbor identifiers for a static VPLS domain. You can configure both static and dynamic neighbors within the same VPLS routing instance.

To configure a static pseudowire for a VPLS neighbor, include the static statement:

You must configure an incoming and outgoing label for the static pseudowire using the incoming-label and outgoing-label statements. These statements identify the static pseudowire’s incoming traffic and destination.

To configure a static pseudowire for a VPLS neighbor, include the static statement at the [edit routing-instances routing-instance-name protocols vpls neighbor address] hierarchy level.

You can also configure the static statement for a backup neighbor (if you configure the neighbor as static the backup must also be static) by including it at the [edit routing-instances routing-instance-name protocols vpls neighbor address backup-neighbor address] hierarchy level and for a mesh group by including it at the [edit routing-instances routing-instance-name protocols vpls mesh-group mesh-group-name neighbor address] hierarchy level.

For a list of hierarchy levels at which you can include the static statement, see the statement summary section for this statement.

To enable static VPLS on a router, you need to either configure a virtual tunnel interface (requires the router to have a tunnel services PIC) or you can configure a label switching interface (LSI). To configure an LSI, include the no-tunnel-services statement at the [edit protocols vpls static-vpls] hierarchy level. For more information, see Configuring VPLS Without a Tunnel Services PIC.

Note:

Static pseudowires for VPLS using an LSI is supported on MX series routers and EX Series switches only. For M series and T series routers, a tunnel services PIC is required.

If you issue a show vpls connections command, static neighbors are displayed with "SN" next to their addresses in the command output.
