# bridge vpls transport-virtual-router

#### Syntax

bridge vplsName vpls transport-virtual-router virtualRouterName

no bridge vplsName vpls transport-virtual-router

#### Release Information

Command introduced in JunosE Release 7.1.0.

#### Description

Configures the transport virtual router for a VPLS instance that uses either BGP or LDP as the signaling protocol. Issuing this command creates a new VPLS instance on the router or causes an existing bridge group to become a VPLS instance. The no version removes the VPLS instance from the router and clears any attributes configured for the deleted VPLS instance.

A VPLS instance is a single instance of the virtual private LAN service (VPLS). VPLS employs a layer 2 virtual private network (VPN) to connect multiple individual LANs across a service provider's MPLS network. The multiple LANs function as a single virtual LAN.

The transport virtual router specifies the name of the virtual router on which the BGP or LDP instance that signals reachability for this VPLS instance is configured.

To create a new VPLS instance or configure an existing bridge group as a VPLS instance, you must issue the bridge vpls transport-virtual-router command before you issue any other commands to configure VPLS attributes; otherwise, the VPLS configuration fails.

#### Options

- vplsName—Name of the new VPLS instance, or name of an existing bridge group specified with the bridge command that you want to configure as a VPLS instance; string of up to 32 alphanumeric characters
- virtualRouterName—Name of the virtual router on which the BGP or LDP instance that signals reachability for this VPLS instance is configured

#### Mode
