Except for the bridge crb and bridge route commands, you can use the existing transparent bridging commands to configure one or more instances of the Virtual Private LAN Service (VPLS), referred to as VPLS instances, on the router. VPLS employs a layer 2 virtual private network (VPN) to connect multiple individual LANs across a service provider’s MPLS core network. The geographically dispersed multiple LANs functions as a single virtual LAN.
A single VPLS instance is analogous to a bridge group, and performs similar functions. In effect, a VPLS instance is a new or existing bridge group that has additional VPLS attributes configured.
For details about configuring and using VPLS, see chapter Configuring VPLS in JUNOSe BGP and MPLS Configuration Guide.
