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 statement:



flood input filter-name;

You can include the flood input statement at the following hierarchy levels:

[edit routing-instances routing-instance-name forwarding-options family vpls]
[edit logical-systems logical-system-name routing-instances routing-instance-name forwarding-options family vpls]
