The pcp third-party-option enable command enables the THIRD_PARTY option.
The undo pcp third-party-option enable command disables the option.
PCP packets in either peer or map mode can carry the THIRD_PARTY option. The presence of the THIRD_PARTY option in a PCP request packet signifies that the specified address, rather than the source IP address of the PCP request packet, should be used as the internal address for the mapping. For the sake of security, the FW supports the THIRD_PARTY option. The FW can process PCP packets carrying the THIRD_PARTY option only after the option is enabled.
By default, this option is disabled.
