An SR-TE LSP with a path definition that includes router R4 as a loose hop and for which Seamless-BFD has been enabled is following the path shown in the exhibit. What happens after router R4 fails if the routers along the path follow the default behavior?

• A.The head end will periodically try to calculate a new path at a rate defined by the retry timer.
• B.The head end will periodically try to calculate a new path at a rate defined by the resignal timer.
• C.The head end will continue forwarding traffic to the current next-hop indefinitely, which will be discarded at the point of failure.
• D.The head end will continue forwarding traffic to the current next-hop indefinitely, and R2 will redirect the traffic to R3 after IGP reconvergence.

Which of the following statements about segment routing fast re-route is FALSE?

• A.Fast re-route is a temporary fix that becomes active for a short period of time after a local network failure.
• B.Fast re-route typically protects the active segment of a tunnel, but under certain conditions it can protect an end-to-end multi-segment tunnel instead.
• C.On a Nokia 7750 SR, R-LFA and TI-LFA can be enabled independently of each other.
• D.The parameter "max-sr-frr-labels" limits the number of labels that R-LFA can add to the data packet encapsulation.
