Applying a VPLS Filter to an Interface

To apply a VPLS filter to an interface, include the filter statement:



filter {
input input-filter-name;
output output-filter-name;
group index;
}

You can include the filter statement at the following hierarchy levels:

[edit interfaces interface-name unit number family vpls]
[edit logical-systems logical-system-name interfaces interface-name unit number family vpls]

In the input statement, list the name of the VPLS filter to be evaluated when packets are received on the interface. In the output statement, list the name of the VPLS filter to be evaluated when packets are transmitted on the interface.

Note: For output interface filters, MAC addresses are learned after the filter action is completed. When an output interface filter’s action is discard, the packet is dropped before the MAC address is learned. However, an input interface filter learns the MAC address before discarding the packet.

For the statement summaries for these statements, see the JUNOS Network Interfaces Configuration Guide.
