    Hi Experts

     

    One of my PE (MX80) is connected to CE (EX4200) switch and VPLS instance is configured for this CE on PE. The EX4200 is connected to the PE via trunk link having 10 VLANS. I want to carry these 10 VLANS from this VPLS instance to remote PE VPLS instance.

     

    My quesiton is that how to bind remote site ID to these 10 VLANS? becuase by default remote site ID is bind to the local interfaces with VLAN ID in the VPLS in order. What is the scalible solution for this scenario that multiple logical interfaces with VLAND ID has to bind with remote site ID?

     

    Thanks

    Hi,

     

    interfaces ge-1/0/0 { flexible-vlan-services; flexible-vlan-tagging; unit 1 { encapsulation vlan-vpls; vlan-id-range 10-19; } }
    routing-instances { customer-c1-v1-to-v1000 { instance-type vpls; vlan-id all; # Note the use of the VLAN id all statement interface ge-1/0/0.1; }
    https://www.juniper.net/techpubs/software/junos/junos93/mx-solutions-guide/one-vpls-instance-for-several-vlans.html
    Please also consider limitations (e.g. you cannot use IRB with this approach).

    Hi,

     

    you can run multiple services (see config sniplet below) on the same phy interface but on different VLANs (VPLS, xSTP, L3 VPN, CCC, L2 VPN etc). flexible-ethernet-services allows you for that.

     

        ae1 {
            flexible-vlan-tagging;
            encapsulation flexible-ethernet-services;
            aggregated-ether-options {
                minimum-links 1;
                link-speed 1g;
            }
            unit 0 {
                encapsulation vlan-ccc;
                vlan-id 103;
                output-vlan-map swap;
            }
            unit 1 {
                encapsulation vlan-bridge;
                vlan-id-range 1000-2000;
            }
            unit 2 {
                encapsulation vlan-bridge;
                vlan-id 101;
            }
            unit 3 {
                encapsulation vlan-ccc;
                vlan-id-range 2500-2800;
                input-vlan-map {
                    swap;
                    vlan-id 2700;
                }
            }
            unit 4 {
                encapsulation vlan-vpls;
                vlan-id-range 3000-3100;
            }
            unit 5 {
                encapsulation vlan-vpls;
                vlan-id-range 3200-3300;
            }
        }

     

    Kind Regards

    Hi Michael

     

    Thanks for the reply. Actually my question was what is flexible-vlan-services not flexible-ethernet-services?

     

    Thanks

    Hello,

     

    well I do not know :). It seems to be a typo in a manual. This command is definitely not available with 10.4 and I am not sure whether it was available any time in the past (I never used it in the past)....

     

    Kind Regards
