bridge vpls rd
Syntax
bridge vplsName vpls rd routeDistinguisher
no bridge vplsName vpls rd
Release Information
Command introduced in JUNOSe Release 7.1.0.
Description
Specifies the unique two-part route distinguisher for a VPLS instance that uses BGP
as the signaling protocol. Because you cannot change or remove the route
distinguisher for a VPLS instance after you set it, issuing the
no version fails, and
causes the router to display an error message.
The following rules apply when you configure the route distinguisher for a VPLS
instance:
■
After you set the route distinguisher for a VPLS instance, you cannot change it
for that VPLS instance. To change the route distinguisher, you must either remove
the transport virtual router configuration from the VPLS instance or delete the
VPLS instance from the router. You can then reconfigure the VPLS instance with
a new route distinguisher.
■
Multiple VPLS instances that use the same transport virtual router cannot have
the same route distinguisher. Conversely, multiple VPLS instances that use
different transport virtual routers can have the same route distinguisher.
The bridge vpls rd 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 rd 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.
