Ethernet Virtual Circuit using Trunk EFP

Trunk EFP can be used to group two or more services instances into one, which can greatly reduce the
configuration burden for large network deployment. Unlike the previous example, only one service instances is
created to bridging the traffic between PEs. In trunk EFP configuration, the second S-Tag will be imposed to the
frame on the trunk link.
