A fully loose LSP "toR6" is configured. All links have the same cost and all routers are Nokia 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?

The LSP will switchover to another path if a failure occurs.
The LSP will switchover to a better path as soon as it is available.
CSPF must be enabled for this LSP to attempt to find a better path.
The LSP will switchover to a better path in a MBB fashion.

Consider the following:

- Router R2 is an ABR in OSPF Areas 0 and 1.

- Router R2 advertises the aggregate prefix 10.10.10.0/24 into Area 1.

- Router R1 in Area 0 generates LDP labels for FECs 10.10.102/31 and 10.10.10.4/31

Router R3 in Area 1 places these FECs in its LIB, but it does not place them in its LFIB. What can you do on router R3 to make it populate these labels in its LFIB?
