For the remainder of this section, R-VPLS and Routed I-VPLS both re described as a VPLS service, and differences are pointed out where applicable.
A standard IP interface within an existing IES or VPRN service context may be bound to a service name. Subscriber and group IP interfaces are not allowed to bind to a VPLS or I-VPLS service context or I-VPLS. A VPLS service only supports binding for a single IP interface.
While an IP interface may only be bound to a single VPLS service, the routing context containing the IP interface (IES or VPRN) may have other IP interfaces bound to other VPLS service contexts of the same type (all VPLS or all I-VPLS). That is, R-VPLS allows the binding of IP interfaces in IES or VPRN services to be bound to VPLS services and Routed I-VPLS allows of IP interfaces in IES or VPRN services to be bound to I-VPLS services.
