bridge vpls route-target
Syntax
[ no ] bridge vplsName vpls route-target { import | export | both } extendedCommunity
Release Information
Command introduced in JUNOSe Release 7.1.0.
Description
Creates or adds to a list of VPN extended communities that the router uses to
determine which routes are imported by a VPLS instance that uses BGP as the
signaling protocol. The
no version removes a route target from the specified list.
A route is imported into the BGP address family for a specified VPLS instance when
both of the following conditions are met:
■
An update message with a route-target export list advertises a route.
■
That list contains at least one route target that matches a route target in the
route-target import list associated with a VPLS instance.
The bridge vpls route-target command is not valid for a VPLS instance that uses
LDP as the signaling protocol. To configure a VPLS instance with LDP signaling, use
the
mpls ldp vpls vpls-id command and the mpls ldp vpls neighbor command.
NOTE: The bridge vpls route-target command is available for a VPLS instance only
after you issue the bridge vpls transport-virtual-router command, which creates the
VPLS instance and configures the transport virtual router.
