This command turns on IGMP proxy or snooping using the specified version. The Multicast Listener
Discovery (MLD) protocol (defined in RFC 2710) is derived from IPv4's Internet Group Management
Protocol version 2 (IGMPv2). MLD uses ICMPv6 message types, rather than IGMP message types.
MLDv1 is equivalent to IGMPv2 and MLDv2 is equivalent to IGMPv3.
Use proxy to have the device use IGMP proxy. Use IGMP snooping to have the DSLAM passively
learn multicast groups.
If you use IGMPv2, the system discards IGMPv3 packets. This provides better security if none of the
devices in the network use IGMPv3. If you select IGMPv3, the system recognizes both IGMPv2 and
IGMPv3.
The following example sets the device to use IGMP proxy with IGMPv2.
30.6.3 multicast igmp qryvid delete Command
Syntax:
multicast igmp qryvid delete <vid>
This command removes an IGMP query VLAN ID. The following example removes IGMP query VLAN
ID 6.
30.6.4 multicast igmp qryvid set Command
Syntax:
ras> multicast igmp qryvid set <vid>
This command adds an IGMP query VLAN ID. When using IGMP proxy mode, the device sends IGMP
queries to the members of the specific VLANs. You can use this command to define which VLANs the
device sends queries only. You must have already used the
vlan commands to create the VLAN
before you use this command.
The following example sets VLAN ID 6 as an IGMP query VLAN.
30.6.5 multicast igmp qryvid show Command
Syntax:
ras> multicast qryvid show
ras> multicast igmp enable proxy igmpv2
ras> multicast igmp qryvid delete 6
ras> multicast igmp qryvid set 6
