Configuring the VPLS MAC Table Timeout Interval

To specify an encapsulation type for the VPLS routing instance, include the
statement:
encapsulation-type
encapsulation-type (ethernet | ethernet-vlan);
You can include this statement at the following hierarchy levels:
[edit routing-instances routing-instance-name protocols vpls]
[edit logical-systems logical-system-name routing-instances routing-instance-name
protocols vpls]
You can also specify an encapsulation type for a specific VPLS neighbor by including the
encapsulation-type statement at the following hierarchy levels:
[edit routing-instances routing-instance-name protocols vpls neighbor address]
[edit logical-systems logical-system-name routing-instances routing-instance-name
protocols vpls neighbor address]
You can specify one or more nondefault routing instances where you want MPLS routes
to be leaked from the mpls.0 path routing table in the master routing instance. This
capability is useful in an L2VPN/VPLS configuration when the remote PE router is learned
from the IGP in a nondefault routing instance, because L2VPN/VPLS installs
ingress-labeled routes only in the master mpls.0 table.
By default, routes in the mpls.0 routing table in the master routing instance are not leaked
to the corresponding routing tables in nondefault routing instances. When L2VPN/VPLS
traffic is received on the core-facing interface in a nondefault routing instance, the router
performs a lookup in the table that corresponds to that interface,
routing-instance-name.mpls.0. Because the routes are not leaked by default, then no
routes are found in the routing-instance-name.mpls.0 routing table and all the incoming
traffic is dropped.
To leak MPLS routes to a nondefault routing instance, include the
statement and specify one or more routing instances where the routes need to be leaked:
import-labeled-routes [ routing-instance-name ];
You can include this statement at the following hierarchy levels:
[edit routing-instances routing-instance-name protocols vpls]
[edit logical-systems logical-system-name routing-instances routing-instance-name
protocols vpls]
You can modify the timeout interval for the VPLS table. We recommend you that configure
longer values for small, stable VPLS networks and shorter values for large, dynamic VPLS
networks. If the VPLS table does not receive any updates during the timeout interval, the
