JN0-363 · Question #55
Referring to the exhibit, you have an established RSVP LSP between R1 and R4 when you experience a link failure between R2 and R3. Which two statements are correct? (Choose two.)
The correct answer is A. R2 sends a ResvTear message upstream to R1 signaling the link failure. D. R3 sends a ResvTear message downstream to R4 signaling the link failure. Upon a link failure in an RSVP-signaled LSP, the router upstream of the failure (R2) sends a PathTear message upstream to the ingress router (R1), and the router downstream of the failure (R3) sends a ResvTear message downstream to the egress router (R4). These messages signal…

Explanation
Upon a link failure in an RSVP-signaled LSP, the router upstream of the failure (R2) sends a PathTear message upstream to the ingress router (R1), and the router downstream of the failure (R3) sends a ResvTear message downstream to the egress router (R4). These messages signal the failure and initiate tear down of the LSP state in the respective directions.
