Routing

Hi Experts

My scenario is like this. I have IP/MPLS core consists of four P routers MX480 and couple of PE routers MX80. My CE is EX4200 whose xe-0/0/0 port is connected to MX80 port xe-0/0/0 port.

EX4200 has couple of VLANS configured VLAN 101, 105, 108, 201. The port xe-0/0/0 of EX4200 (connected to MX80 port xe-0/0/0) is configured as trunk and all VLAN are allowed means VLAN 101, 105, 108, 201 are allowed on that trunk.

I want to configure the VPLS instance on MX80 to carry all these VLANS to remote PE. I would appreciate if some body give me configuration for this scenario for VPLS instance with recommended options if no of VLANS are more than I mentioned here.

Thanks

Hi,

if you want to transfer all VLANs on a trunk then look into following config (interface ge-1/3/1 on PE3 side; ignore interop part):

OK great. It means in the VPLS instance I do not need to mention any VLAN related configuration? But If I want to allow specific VLAN not all VLAN then what would be the configuration?

Thaks

Then you would have something like 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;
        }

routing-instances {

    L2TRANSPARENT {
        instance-type vpls;
        vlan-id all;
        interface ae1.4;
        interface ae1.5;
        vrf-target target:65000:200;
        protocols {
            vpls {
                no-tunnel-services;
                site A {
                    automatic-site-id;
                }
            }
        }
    }
