Description
Specify the amount of time (in seconds) that an LSP must wait before traffic reverts to a primary path. If during this time the primary path experiences any connectivity problem or stability problem, the timer is restarted.
If you have configured BFD on the LSP, the Junos OS waits until the BFD session is restored before starting the revert timer counter.
If you have configured a value of 0 seconds for the revert-timer statement and traffic is switched to the secondary
path, the traffic remains on that path indefinitely. It is never switched
back to the primary path unless you intervene.
