Virtual Private LAN Service
To support L2CP protocols running on top of a LAG, m-VPLS SAPs must be created
on the LAG itself.

The v-VPLS forwarders emulate the ISAM bridging service in the IHUB. Typical of
bridging, a v-VPLS operates in the context of a VLAN. In general, several v-VPLS will
be configured allowing to support a multi-VLAN environment.

The v-VPLS can be used for the following functionality:
•
•
A v-VPLS has no operational state. It is configured with an associated customer ID
and VLAN ID, to enable the forwarding of traffic. SAPs are used to associate the
v-VPLS instance with specific residential (user) or regular (network) access ports or
hybrid ports.
