    Configuring the VLAN Interface, IRB Interface, and Bridge Domain for MX Series Router Draft-Rosen Multicast VPN Cloud CPE Services

    To configure the VLAN interface, IRB interface, and bridge domain:

    1. Configure the physical interface for VLAN tagging and flexible Ethernet services encapsulation.
      [edit]user@host# edit interfaces ge-1/0/1 user@host# set vlan-tagginguser@host# set encapsulation flexible-ethernet-services
    2. Configure the subscriber VLAN.
      1. Configure the logical interface.
        [edit interfaces ge-1/0/1]user@host# edit unit 106
      2. Configure the encapsulation for the logical interface.
        [edit interfaces ge-1/2/3 unit 106]user@host# set encapsulation vlan-bridge
      3. Bind an 802.1Q VLAN tag ID to the logical interface.
        [edit interfaces ge-1/0/1 unit 106]user@host# set vlan-id 106
      4. Configure the logical interface for Layer 2 bridging.
        [edit interfaces ge-1/0/1 unit 106]user@host# set family bridge
    3. Configure the IRB interface.
      1. Configure the logical interface used for internal VPN traffic as the IRB interface.
        [edit]user@host# edit interfaces irb unit 106
      2. Specify the private subnet of the VPN site on the IRB interface.
        [edit interfaces irb unit 106]user@host# set family inet address 10.132.12.1/24
    4. Configure the bridge domain.
      1. Configure the bridge domain name and set the domain type to bridge.
        [edit]user@host# edit bridge-domains vlan-106 domain-type bridge
      2. Associate the subscriber’s VLAN ID with the bridge domain.
        [edit bridge-domains vlan-106]user@host# set vlan-id 106
      3. Specify the interface name for the bridge domain.
        [edit bridge-domains vlan-106]user@host# set interface ge-1/0/1.106
      4. Specify the routing interface to include in the bridge domain.
        [edit bridge-domains vlan-106]user@host# set routing-interface irb.106
    5. (Optional) If there are multiple Layer 2 interfaces in the same bridge domain, enable IGMP snooping in the bridge domain.
      [edit bridge-domains vlan-106]user@host# set protocols igmp-snooping
