Subject: [PWE3] Use of service-delimiting tag on Egress PE

Hi everyone

    In the Ethernet tagged mode, why should the service-delimiting tag
be present in the frame sent over the PW if its function is for the
Ingress PE to select a PW ? In other words, what is its purpose at the
Egress PE as according to PWE3-Ethernet-encap draft, "In both modes, the
service-delimiting tag values have only local significance, i.e., are
meaningful only at a particular PE-CE interface." If there is any use as
the draft suggests, can anyone please give an example.

TIA,

Asheesh
