    1 Configure VLAN 10 on the SHub so that multicast traffic can be delivered to all LT units:

    configure vlan shub id 10 mode residential-bridge

    configure vlan shub id 10 egress-port network:2

    configure vlan shub id 10 egress-port lt:1/1/[4…7]

2 Configure VLAN 10 on the NT subsystem:

    configure vlan id 10 mode residential-bridge

    3 Configure the multicast source table on the NE. This table contains the list of all multicast groups available to subscribers and the corresponding VLAN group for each multicast group.

    configure mcast src 224.1.1.[1…100] vlan-id 10

    atm-peak-bit-rate 0 atm-sus-bit-rate 0

    4 Configure the system to disallow the joining of unconfigured multicast groups for iBridge subscribers:

    configure mcast general no package-member [1...1024]

    configure mcast capacity max-num-uncfg 0

    5 Set the maximum number of unique groups that can be active on a single LT unit: configure mcast capacity max-num-group 256

    6 Start the IGMP system and configure the IP address used for IP messaging toward the subscribers and the SHub. This address is not used for messaging toward the router.

    configure igmp system src-ip-address 192.168.1.1 start

    7 Configure the VLAN IP address used for IGMP messaging toward the upstream router:

    configure interface shub vlan-id 10 admin-status down

    configure interface shub ip 10 ip-addr 10.10.10.1/24

    configure interface shub vlan-id 10 admin-status up

8 Enable snooping on the SHub:

    configure igmp shub igs-system enable-snooping

    9 Configure the port and VLAN ID connection for the router upstream of the NE: configure igmp shub vlan-router-port 10 network-port 2

    query-timer 125

    10 Disable the snooping filter on the multicast VLAN. This step enables snooping on the VLAN.

    configure igmp shub vlan-filter 10 no snoop-filter

11 Enable the snooping filter on the subscriber VLANs. This disables snooping on the

    VLANs, since there should be no IGMP on these VLANs.

    configure igmp shub vlan-filter [101…124] snoop-filter

    configure igmp shub vlan-filter [201…224] snoop-filter

    configure igmp shub vlan-filter [301…348] snoop-filter

    configure igmp shub vlan-filter [401…448] snoop-filter

12 Enable IGMP on the subscriber interface and limit the maximum number of multicast

    groups to which a subscriber can belong at any one time: configure igmp channel 1/1/4/[1...24] max-num-group 10 configure igmp channel 1/1/5/[1...24] max-num-group 10 configure igmp channel 1/1/6/[1...48]:8:35 max-num-group 10 configure igmp channel 1/1/7/[1...48]:8:35 max-num-group 10

13 STOP. This procedure is complete.

    Subscribers can now join configured multicast groups from xDSL ports using IGMP.
