    Hello,


    I have configured a l2circuit connection between two EX 4600.
    On Customer Side A I configured a douple tag VLAN:
    flexible-vlan-tagging;
    unit 1002 {
    description "Test 4";
    vlan-tags outer 0x8100.1002 inner 0x8100.110;
    family inet {
    address 172.26.3.2/30;

    The EX4600 on side A is configured as follow:
    flexible-vlan-tagging;
    encapsulation vlan-ccc;
    unit 1002 {
    description "Test 4";
    encapsulation vlan-ccc;
    vlan-id 1002;
    family ccc {
    filter {
    input 100m-ff;
    }
    }
    }

    On Side B I want to remove the outer VLAN tag on the EX4600 so that the customer only gets the C-VLAN:
    flexible-vlan-tagging;
    encapsulation vlan-ccc;
    unit 1002 {
    description "Test 4";
    encapsulation vlan-ccc;
    vlan-id 1002;
    input-vlan-map push;
    output-vlan-map pop;
    }

    If the C-VLAN ID 110 is configured for customer B, I can see the address 172.26.3.2 in the ARP, but I cannot ping it.
    At customer device A. the arp is empty.

    If S-VLAN + C-VLAN is configured on both sides, it works and via "monitor traffic layer2-headers" I can also see both tags.

    It looks like the EX4600 on side B will not add the Outer S-VLAN 1002.

    Does adding / removing the vlan id have to be configured differently?
    In addition, several single tagged vlans are to be transferred to the interface.


    Thanks for your support!
