Specify the fast reroute priority for a VPLS routing instance. You can configure
, or fast reroute priority to prioritize specific VPLS routing instances for faster
medium low
convergence and traffic restoration. Because the router repairs next hops for high-priority
VPLS routing instances first, the traffic traversing a VPLS routing instance configured
with high fast reroute priority is restored faster than the traffic for VPLS routing instances
configured with or
medium
NOTE: In the VPLS documentation, the word router in terms such as PE router
is used to refer to any device that provides routing functions.
low
—Set the fast reroute priority for a VPLS routing instance to high. During a fast reroute
high
event, the router repairs next hops for high-priority VPLS routing instances first.
low —Set the fast reroute priority for a VPLS routing instance to low, which is the default.
During a fast reroute event, the router repairs next hops for low-priority VPLS routing
instances last.
—Set the fast reroute priority for a VPLS routing instance to medium. During a
medium
fast reroute event, the router repairs next hops for medium-priority VPLS instances
after high-priority VPLS routing instances but before low-priority VPLS routing
instances.
