Description (partial)

Symptoms: MPLS-TE tunnel label reallocation on midpoint router occurs while
RSVP is gracefully restarting due to CPU switchover.

Conditions: Occurs on a Cisco 7600 that is configured as the midpoint router
when the upstream node is a Cisco IOS-XR router. This does not happen if the
upstream node is also a Cisco IOS router. Because of this label re-allocation,
traffic downtime is ~100 msec
