The M Series routing platforms continue to support only inet traffic for Layer 2.5
VPNs.

■ New configuration statement for removing dynamically learned MAC
addresses from the MAC address database—Media access control (MAC) flush
processing removes MAC addresses from the MAC address database that have
been learned dynamically. With the dynamically learned MAC addresses removed,
MAC address convergence requires less time to complete.
In this release, you enable MAC flush processing for the virtual private LAN
service (VPLS) routing instance or for the mesh group under a VPLS routing
instance by using the mac-flush statement instead of the mac-tlv-receive and
mac-tlv-send statements.
mac-flush [ explicit-mac-flush-message-options ];
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]
NOTE: The mac-tlv-receive and mac-tlv-send statements were removed from
Release 10.0 of the JUNOS Software and are no longer visible in the [edit
logical-systems logical-system-name routing-instances routing-instance-name protocols vpls]
and [edit routing-instances routing-instance-name protocols vpls] hierarchy levels.
Although the mac-tlv-receive and mac-tlv-send statements are recognized in the current
release, they will be removed in a future release. We recommend that you update
your configurations and use the mac-flush statement.
To also configure the router to send explicit MAC flush messages, you can include
explicit-mac-flush-message-options with the statement:
■
any-interface—(Optional) Send a MAC flush message when any
customer-facing attachment circuit interface goes down.
■
any-spoke—(Optional) Send a MAC FLUSH-FROM-ME flush message to all
provider edge (PE) routers in the core when one of the spoke pseudowires
between the multitenant unit switch and the other network-facing provider
