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.
