Description
Specify the fast reroute priority for a VPLS routing
instance. You can configure high, medium, or low fast reroute priority to prioritize specific VPLS routing
instances for faster 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 medium or low fast reroute priority.
In the VPLS documentation, the word router in terms such as PE router is used to refer to any device that provides routing functions.
Default
low
Options
high—Set the fast reroute priority
for a VPLS routing instance to high. During a fast reroute 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.
medium—Set the fast reroute priority for a
VPLS routing instance to medium. During a 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.
Required Privilege Level
