    Hi All

     

    My customer will have a central office at HK and will connect to other pops bt l2circuit.

     

    Now his central  connect to my router(MX1) with a trunk port(10G) in HK. And a Korea office connecto my router(MX2) with access port (1G) with tagging vlan 10 .

     

    In the future , he will have other pop and joni this l2circuit group as point-to-multipoint

    But I only let him connect only vlan10 by point-to-point. How do I modify it on my MX or is there any documnet to reach it ?

     

    Please refer to this attachment.

    Thanks

    Hello,

    Use LDP VPLS on Your MX.

    https://www.juniper.net/documentation/en_US/junos12.3/topics/task/configuration/vpls-ldp-signaling-solutions.html

    Customer can keep his L2circuit config on his side.

    HTH

    Thx

    Hello 

     

    Thanks for your sharing.

     

    I have one more question. Can I add one more unit with vlan-ccc and vlan id 11 in HK and connec to other pops like Japan with the same configuration ?

     

    Then in HK have two vlan 10,11 connect to vlan 10 in Korea and vlan11 in Japan.

    Is it possbile to do that ?

     

    The configuration in HK like as follow :

    neighbor 192.198.144.6 {

        interface xe-2/1/3.10 {

            virtual-circuit-id 10002;

            control-word;

            mtu 8800;

            encapsulation-type ethernet-vlan;

            ignore-mtu-mismatch;

            pseudowire-status-tlv;

        }

     

      interface xe-2/1/3.11 {

            virtual-circuit-id 10003;

            control-word;

            mtu 8800;

            encapsulation-type ethernet-vlan;

            ignore-mtu-mismatch;

            pseudowire-status-tlv;

        }

    }

     

    > show configuration interfaces xe-2/1/3   

    vlan-tagging;

    mtu 8880;

    encapsulation vlan-ccc;

    unit 10 {

        vlan-id 10;

    }

    unit 11 {

        vlan-id 11;

    }

     

    Best regards,

    Hello,

    Of course it is possible to add an extra Type-4 L2circuit (meaning neighbor IP+ VC id + CCC logical interface) for each customer VLAN.

    However, if You do a VLAN-list + L2circuit Type-5  as below You don't need to repeat the full L2circuit config each time a customer adds a VLAN, You only need to update the vlan-id-list. The downside is that L2circuit briefly bounces when You add/remove a VLAN-id from the list.

    interfaces {
        ge-0/0/7 {
            vlan-tagging;
    	mtu 8880;
            encapsulation extended-vlan-ccc;
            unit 6021 {
                vlan-id-list [ 10 11 15 25 2025 3225 ];
                family ccc;
            }
        }
    }
    protocols {
        l2circuit {
            neighbor 169.254.0.111 {
                interface ge-0/0/7.6021 {
                    virtual-circuit-id 1010;
                    no-control-word;
                    encapsulation-type ethernet;
                    ignore-mtu-mismatch;
                }
            }
        }
    }

    Of course, the L2circuit tailend should have the same Type-5 L2circuit config.

    HTH

    Thx

    Hello

     

    If it is trunk port with two vlan in HK , but one to KR and another one to JP, Can I set as follow in HK ?

     

    neighbor 192.198.144.6 {

        interface xe-2/1/3.10 {

            virtual-circuit-id 10002;

            control-word;

            mtu 8800;

            encapsulation-type ethernet-vlan;

            ignore-mtu-mismatch;

            pseudowire-status-tlv;

        }

     

    neighbor 192.198.149.6 {

        interface xe-2/1/3.11 {

            virtual-circuit-id 10003;

            control-word;

            mtu 8800;

            encapsulation-type ethernet-vlan;

            ignore-mtu-mismatch;

            pseudowire-status-tlv;

        }

     

     

    show configuration interfaces xe-2/1/3   

    vlan-tagging;

    mtu 8880;

    encapsulation vlan-ccc;

    unit 10 {

             encapsulation vlan-ccc;    

             vlan-id 10;

    }

    unit 11 {

             encapsulation vlan-ccc;    

             vlan-id 11;

    }

     

     

    Many thanks
