Context config>service>vpls>spoke-sdp
config>service>vpls>mesh-sdp
Description
This command specifies an explicit dot1q value used when encapsulating to the SDP far end. When
signaling is enabled between the near and far end, the configured dot1q tag can be overridden by a
received TLV specifying the dot1q value expected by the far end. This signaled value must be stored
as the remote signaled dot1q value for the binding. The provisioned local dot1q tag must be stored as
the administrative dot1q value for the binding.
When the dot1q tag is not defined, the default value of zero is stored as the administrative dot1q
value. Setting the value to zero is equivalent to not specifying the value.
The no form of this command disables the command
