Juniper JUNOSE 11.2.X BGP AND MPLS, Configuration Manual

Page: 627 / 742

To configure a basic VPLS instance with BGP signaling on the PE router:
1.
From Global Configuration mode, create the VPLS instance by specifying the transport
virtual router for this instance.
host1(config)# bridge customer1 vpls transport-virtual-router vr1
If the bridge group you specify (customer1 in this example) already exists on the
router, issuing this command causes the bridge group to become a VPLS instance.
NOTE: To configure a VPLS instance, you must issue the bridge vpls
transport-virtual-router command before you issue any of the other bridge vpls
commands in this procedure. If the bridge vpls transport-virtual-router command is
not issued first, the other bridge vpls commands fail.
2.
Specify the maximum number of customer sites that can participate in the VPLS
domain represented by the VPLS instance. (By default, a VPLS domain must consist
of at least one site.)
host1(config)# bridge customer1 vpls site-range 15
3.
Specify a name and unique identifier for the customer site that belongs to the VPLS
instance.
host1(config)# bridge customer1 vpls site-name westford site-id 1
The site ID value must be greater than zero and be unique across the VPLS domain.
This is not true for a multihomed customer site. See “Configuring BGP Multihoming
for VPLS” on page 592 for more information.
4.
Specify the unique, two-part route distinguisher (RD) for the VPLS instance.
host1(config)# bridge customer1 vpls rd 100:11
In this example, the first number in the route distinguisher (100) is the number of the
AS in which the extended community resides. The second number in the route
distinguisher (11) uniquely identifies the VPLS instance within the AS.
TIP: You cannot change or remove the route distinguisher for a VPLS instance after
you set it; for this reason the no bridge vpls rd command fails. . 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.
5.
Create or add a route target to the import and export lists of VPN extended
communities for this VPLS instance.
host1(config)# bridge customer1 vpls route-target both 100:1
The PE router uses the lists of VPN extended communities to determine which routes
are imported by this VPLS instance.
