vMX Layer 2 Bridging

Hi all,

Today lets play layer 2 bridging with vMX from Juniper Network

==================================================================

interfaces {
    ge-0/0/0 {
        description "MANAGEMENT PORT PLEASE DO NOT DELETE";
        mac 00:0c:29:44:95:2d;
        unit 0 {
            family inet {
                address 10.210.14.31/24;
            }
        }
    }
    ge-0/0/1 {
        mac 00:0c:29:44:95:37;
        unit 0 {
            family bridge {
                interface-mode trunk;
                vlan-id-list 100;
            }
        }
    }
    ge-0/0/2 {
        mac 00:0c:29:44:95:41;
        unit 0 {
            family bridge {
                interface-mode trunk;
                vlan-id-list 100;
            }
        }
    }
  irb {
        unit 100 {
            family inet {
                address 90.1.1.1/24;
            }
        }
        unit 200 {
            family inet {
                address 90.1.1.2/24;
            }
        }
    }
}
routing-instances {

        interface ge-0/0/1.0;

Interface routing and bridging can communicate with each other to one vMX

you can expand to add more tenant connect to the instances..... and more vlans also

it was just and examples... :))
