Next hops for medium-priority VPLS routing instances are repaired.
2.
Next hops for low-priority VPLS routing instances are repaired.
3.
Because next hops for VPLS routing instances configured with
are repaired first, the traffic traversing high-priority VPLS instances is restored faster than
the traffic for VPLS instances configured with
ability to prioritize specific VPLS routing instances for faster convergence and traffic
restoration enables service providers to offer differentiated service levels to their
customers.
Within a particular fast reroute priority level (
for traffic restoration of VPLS routing instances is followed.
NOTE: VPLS fast reroute priority is not supported on J Series routers.
To configure ,
high medium
the statement:
fast-reroute-priority
fast-reroute-priority (high | medium | low);
You can include this statement at the following hierarchy levels:
[edit forwarding-options]
[edit logical-systems logical-system-name routing-instances routing-instance-name
forwarding-options]
[edit routing-instances routing-instance-name forwarding-options]
You can configure fast reroute priority only for routing instances with the
set to vpls . If you attempt to configure fast reroute priority for a routing instance with an
other than
instance-type vpls
fails.
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.
The following example snippet shows configuration of
VPLS routing instance named
test-vpls {
instance-type vpls;
forwarding-options {
fast-reroute-priority
}
}
To display the fast reroute priority setting configured for a VPLS routing instance, use
the
show route instance detail
command, see the
