Description

Traffic loss is seen fter adding "vlan-id all" to a VPLS instance.

 

The configuration tied to the instance is as follows:

 

 VPLS-TEST {

    protocols {

      vpls {

        mac-table-size {

          1000;

        }

        interface-mac-limit {

          100;

        }

        site VPLS-TEST_001 {

          interface xe-200/0/60.990;

          site-identifier 1;

        }

        no-tunnel-services;

      }

    }

    description "VPLS-TEST";

    instance-type vpls;

    vlan-id all;

    forwarding-options {

      family vpls {

        flood {

          input Flood_only;

        }

      }

    }

    interface xe-200/0/60.990;

    route-distinguisher 66666:111111;

    vrf-target {

      import target:66666:111111;

      export target:66666:111111;

    }

  }

 

------------------------------------------  

 xe-200/0/60 {

    description "VPLS-TEST";

    disable;

    flexible-vlan-tagging;

    mtu 9100;

    encapsulation flexible-ethernet-services;

    unit 5 {

      apply-groups-except [ uRPF_interface ARP_interface ];

      disable;

      description "Inband NID / CPE";

      encapsulation vlan-bridge;

      vlan-id 5;

    }

    unit 990 {

      apply-groups-except [ uRPF_interface ARP_interface ];

      disable;

      description "VPLS-TEST"";

      encapsulation vlan-vpls;

      vlan-id 990;

      input-vlan-map pop;

      output-vlan-map push;

      family vpls {

        filter {

          input vpls_edge_filter;

        }

      }

    }

  }

 

After vlan-id all was added, l2 and l3 traffic stopped being forwarded by the router.

Symptoms

L2 and L3 traffic will not work due to "vlan-id all" knob

Solution

As a workaround, 'vlan-id all' can be removed.
