Configuring a Filter for Flooded Traffic

You can configure a VPLS filter to filter flooded packets. CE routers typically flood the
following types of packets to PE routers in VPLS routing instances:
Layer 2 broadcast packets
Layer 2 multicast packets
Layer 2 unicast packets with an unknown destination MAC address
Layer 2 packets with a MAC entry in the DMAC routing table
You can configure filters to manage how these flooded packets are distributed to the
other PE routers in the VPLS routing instance.
To apply a flooding filter to packets arriving at the PE router in the VPLS routing instance,
and specify the filter, include the
flood input filter-name;
You can include this statement at the following hierarchy levels:

You can configure a policer for VPLS traffic. The VPLS policer configuration is similar to
the configuration of any other type of policer.
VPLS policers have the following characteristics:
You cannot police the default VPLS routes stored in the flood table from PE
router–sourced flood traffic.
When specifying policing bandwidth, the VPLS policer considers all Layer 2 bytes in a
packet to determine the packet length.
