A fully loose LSP "toR6" is configured. All links have the same cost and all routers are Alcatel- Lucent 7750 SRs. The LSP currently traverses the path R1-R2-R7-R8-R4-R6 and the resignal timer is enabled. Which of the following about this LSP is FALSE?

A. The LSP will switchover to another path if a failure occurs.

B. The LSP will switchover to a better path as soon as it is available.

C. CSPF must be enabled for this LSP to attempt to find a better path.

D. The LSP will switchover to a better path in a MBB fashion.

A. The time router R2 takes to receive a PATH Error message from router R4.

B. The time router R2 takes to find out a number of RSVP Hello messages have been missed.

C. The time router R2 takes to send a PATH Tear message to the head-end router.

D. The time router R2 takes to receive a PATH message from router R4 after a PATH refresh interval.
