ISAM supports configuration of SAPs on Ethernet access or hybrid ports. A v-VPLS
uses Ethernet dot1q encapsulated SAPs exclusively, to handle VLAN ID tagged
traffic received on the regular (network) or residential (user) access/hybrid port
defined by the SAP associated with the v-VPLS. See Residential and regular port
usage for more information.
The ISAM supports dot1q encapsulation at network side for v-VPLS. A frame that is
multiple-tagged with the specified VLAN Id as the most exterior tag, will be handled
by the v-VPLS, since the interior VLAN tag is transparent. As such, the v-VPLS
forwards single- and multiple-tagged frames.
The v-VPLS processes untagged non-L2CP frames, by configuring an SAP for the
v-VPLS with a null VLAN ID defined. In this case, untagged non-L2CP traffic is
handled by the v-VPLS, as if it were tagged with the v-VPLS VLAN ID.

v-VPLS SAPs

Untagged L2CP traffic is handled by the m-VPLS.

Although v-VPLS forwards single- and

multiple-tagged frames, the messages generated by the
v-VPLS itself are single tagged. This is the case for instance for
IGMP messages generated by the v-VPLS when acting as
proxy IGMP client. Then if, for instance, a multi-tagged query
message would be received, the answer on this query message
will be single tagged.
