R3721-F3210-F3171-HP High-End Firewalls Network Management Command Reference-6PW101

543
This command takes effect only after IP multicast routing is enabled on the corresponding instance.
If IGMP proxying is enabled on a loopback interface, the proxy device maintains only the IGMP routing
table without adding the IGMP routes to the multicast routing table and forwarding table.
Related commands: multicast routing-enable.
Examples
# Enable IP multicast routing in the public network and enable IGMP proxying on GigabitEthernet 0/1.

Description
Use igmp proxying forwarding to enable a non-querier downstream interface to forward multicast traffic.
Use undo igmp proxying forwarding to disable the forwarding capability of a non-querier downstream
interface.
By default, a non-querier downstream interface does not forward multicast traffic.
Examples
# Enable the multicast forwarding capability on GigabitEthernet 0/1, a non-querier downstream
interface on the IGMP proxy device.
<Sysname> system-view
[Sysname] interface gigabitethernet 0/1
