No RSVP end-to-end will occur.

Communications Manager will use local RSVP.

Explanation:
Incorrect answer: ABC

A possible cause is that the same router is being used as the calling and called RSVP agents, and that
router is not running the latest IOS version, which supports loopback on RSVP reservation. Make
sure that the router is running the latest IOS version.
