    Defining a VPLS Firewall Policer

    You can configure filters, policers, and broadcast and unknown filters to determine which kind of traffic is allowed into and out of a VPLS domain. You can apply these filters and policers to CE-facing interfaces only.

    To process traffic as it enters a VPLS domain, you can define a firewall policer and apply it to the input interface. To define policer characteristics for incoming VPLS traffic, include the bandwidth-limit and burst-size-limit statements at the [edit firewall policer policer-name if-exceeding] hierarchy level. Then, specify statements to implement the desired action (for example, discard) for the policed traffic at the [edit firewall policer policer-name then] hierarchy level. To apply the policer to a CE-facing interface, include the input or output statements and the name of the policer at the [edit interfaces interface-name unit unit-number family vpls policer] hierarchy level.

    [edit]
    interfaces {ge-2/1/0 {vlan-tagging;mtu 1544;encapsulation vlan-vpls;unit 0 {encapsulation vlan-vpls;vlan-id 600;family vpls {policer {input vpls-policer;}}}}}
    firewall {policer {vpls-policer {if-exceeding {bandwidth-limit 5m;burst-size-limit 1m;}then discard;}}}
