RRO is used to report the protection tunnel status to the head-end router.

RRO contains the MP information that is required by a PLR for facility protection.

RRO contains the label information that is expected by an MP for facility protection.

RRO is used to inform downstream routers about the protection type requested.

The PLR issues an RSVP PATH message to the tail-end requesting the address of the MP.

The PLR learns the address of the MP from the ERO.

The PLR learns the address of the MP from the RRO.

The PLR learns the address of the MP from the targeted RSVP Hello message.

The PLR knows the address of the MP is the same as the tail-end router.

After a new path for LSP-1 is established on R1-R3-R5-R6, the old path is torn down.

After the old path for LSP-1 is torn down, the new path is established on R1-R3-R5-R6.

LSP-1 will stay on R1-R2-R4-R6 because there is enough bandwidth on the existing path.

LSP-1 will be torn down because CSPF fails to find a new path.
