Layer 2 IGMP (Snooping and Query)
– 482 –
◆ Proxy Query Address – A static source address for locally generated query and
report messages used by IGMP Proxy Reporting. (Range: Any valid IP unicast
address; Default: 0.0.0.0)
IGMP Snooping uses a null IP address of 0.0.0.0 for the source of IGMP query
messages which are proxied to downstream hosts to indicate that it is not the
elected querier, but is only proxying these messages as defined in RFC 4541.
The switch also uses a null address in IGMP reports sent to upstream ports.
Many hosts do not implement RFC 4541, and therefore do not understand
query messages with the source address of 0.0.0.0. These hosts will therefore
not reply to the queries, causing the multicast router to stop sending traffic to
them.
To resolve this problem, the source address in proxied IGMP query messages
can be replaced with any valid unicast address (other than the router’s own
address).
Web Interface
To configure IGMP snooping on a VLAN:
1. Click Multicast, IGMP Snooping, Interface.
2. Select Configure VLAN from the Action list.
3. Select the VLAN to configure and update the required parameters.
4. Click Apply.
