Configuring VPLS Fast Reroute Priority

To clear dynamically learned MAC addresses globally across all devices participating in
the routing instance, you can include the statement at the following hierarchy levels:
[edit logical-systems logical-system-name routing-instances routing-instance-name
protocols vpls]
[edit routing-instances routing-instance-name protocols vpls]
To clear the MAC addresses on the routers in a specific mesh group, you can include the
statement at the following hierarchy levels:
[edit logical-systems logical-system-name routing-instances routing-instance-name
protocols vpls mesh-group mesh-group-name]
[edit routing-instances routing-instance-name protocols vpls
mesh-group mesh-group-name]

For certain cases where MAC flush processing is not initiated by default, you can also
specify
explicit-mac-flush-message-options
explicit MAC flush messages under specific conditions. For a list of the explicit MAC flush
message options you can include with this statement, see the summary section for this
statement.

When a path is rerouted after a link failure by using the MPLS fast reroute feature, the
affected next hops are repaired by switching them from the active label switched path
(LSP) to the standby LSP. To specify the order in which the next hops are repaired and
traffic convergence is restored for VPLS routing instances after a fast reroute event, you
can use the
fast-reroute-priority
priority for a VPLS routing instance. By default, the fast reroute priority for a VPLS routing
instance is low .
Next hops are repaired and known unicast, unknown unicast, broadcast, and multicast
traffic for VPLS routing instances are restored in the following order, based on the fast
reroute priority configuration:
Next hops for high-priority VPLS routing instances are repaired.
