d. Activate the neighbors in the L2VPN address family for the PE-to-PE BGP
session.
e. Create the VPWS address family to configure the router to exchange layer
2 NLRI for each VPWS instance configured on the router.

Configuring a VPWS Instance
You must configure a VPWS instance for each L2VPN in which the router participates.
From a configuration standpoint, a VPWS instance is simply a new L2VPN that you
configure with additional VPWS L2VPN attributes.
Table 101 on page 659 lists the commands that you use to configure a basic VPWS
instance.
