service tunnel encapsulation labeling as service traffic.
If remote-sdp is specified, the far-end responder attempts to use an egress SDP-ID bound to the
service with the message originator as the destination IP address with the VC-Label for the
service. The SDP-ID defines the encapsulation of the SDP tunnel encapsulation used to reply to
the originator; this can be IP/GRE or MPLS. On responder egress, the Service-ID must have an
associated VC-Label to reach the originator address of the SDP-ID and the SDP-ID must be
operational for the message to be sent.
If remote-sdp is not specified, the svc-ping request message is sent with GRE encapsulation
with the OAM label.
The table below indicates how the message response is encapsulated based on the state of the
remote Service ID.
