Parameters cdp — Specifies the Cisco discovery protocol.
dtp — Specifies the digital trunking protocol.

def-mesh-vc-id
Syntax [no] def-mesh-vc-id vc-id
Context config>service>vpls
Description This command configures the value used by each end of a tunnel to identify the VC. If this command
is not configured, then the service ID value is used as the VC-ID.
This VC-ID is used instead of a label to identify a virtual circuit.The VC-ID is significant between
peer nodes on the same hierarchical level. The value of a VC-ID is conceptually independent from the
value of the label or any other datalink specific information of the VC.
The no form of this command disables the VC-ID.
Default none
Parameters vc-id — Specifies the default mesh vc-id.
