Router R4 originates 500 RSVP signaled LSPs with default hello and refresh timer settings If the only downstream communication fails (link is operationally UP), how long will RSVP wait before it declares the RSVP sessions down?

RSVP (Resource Reservation Protocol) typically uses a default hello interval of 3 seconds and will attempt to send hello messages with a retry limit of 3 times before declaring the session down. This means the total time before RSVP declares the sessions down would be 3 seconds per hello message multiplied by 3 retries, which equals 9 seconds or 9000 milliseconds.
Default RSVP hello timer is 3 seconds with a limit of 3 retries. Session is torn down after 3*3=9 seconds=9000 ms
