This object specifies the source IP address of the dynamic decap tunnel, the signaled counterpart to the static decap tunnel's source address, as the description states. Unlike the static version, this value is learned dynamically as part of RSVP-TE signaling rather than manually configured, so an unexpected value here reflects the actual signaled path rather than a typo in local configuration. For example, this field populating with the address of a specific remote PE confirms which ingress point actually signaled the LSP terminating at this router.
