PORT-shared EVPL services
As shown in
, the services of different users are accessed through a PORT at a station,
and are then isolated from each other by using the VLAN IDs. Services are transmitted to other
PORTs at this station through different VCTRUNKs.

VCTRUNK-shared EVPL services Ethernet boards support the convergence and
distribution of EVPL services by using the following modes:
–
VLAN tag-based convergence and distribution of EVPL services
–
QinQ technology-based convergence and distribution of EVPL services
, the services of different users are isolated by using the VLAN/QinQ
scheme. Hence, the services of different users can be transmitted in the same VCTRUNK.
