1. Create the VPWS instance by configuring the encapsulation type for all interfaces
in the L2VPN.
You must issue this command before any other l2vpn commands.
host1(config)#l2vpn exampleco encapsulation-type ethernet
2. Configure the maximum number of customer sites that can participate in the
L2VPN.
host1(config)#l2vpn exampleco site-range 10
3. Configure the name and ID number for the customer sites in the L2VPN instance.
The site ID value must be greater than zero and be unique within the L2VPN for
that customer site. This is not true for a multihomed customer site. See
“Configuring BGP Multihoming for VPWS” on page 661 for more information.
host1(config)#l2vpn exampleco site-name westford site-id 1
4. Configure a route distinguisher for the L2VPN.
In this example, the first number in the route distinguisher (100) is the number
of the autonomous system (AS). The second number in the route distinguisher
(11) uniquely identifies the L2VPN instance within that AS.
host1(config)#l2vpn exampleco rd 100:11
5. Create or add a route target to the import and export lists of the L2VPN’s
route-target extended community.
The PE router uses the lists to determine which routes are imported into the
VPWS instance.
host1(config)#l2vpn exampleco route-target both 100:1
6. Specify the local preference for use of the control word and sequencing for the
layer 2 packets encapsulated in the MPLS packets that are sent to the remote PE
router.
host1(config)#l2vpn exampleco control-word
host1(config)#l2vpn exampleco sequencing
