IGMP AND IGMP SNOOPING COMMANDS
IP
IGMP PROXY-SERVICE
ip igmp proxy-service
Overview Use this command to enable an interface to be the upstream IGMP proxy-service
interface for the device. All associated downstream IGMP mroute proxy interfaces
on this device will have their memberships consolidated on this proxy service
interface, according to IGMP host-side functionality.
Use the no variant of this command to remove the designation of the interface as
an upstream proxy-service interface.
Syntax
ip igmp proxy-service
no ip igmp proxy-service
Mode Interface Configuration for a VLAN interface.
Usage notes This command applies to VLAN interfaces configured for IGMP Proxy.
This command is used with the ip igmp mroute-proxy command to enable
forwarding of IGMP reports to a proxy service interface for all forwarding entries for
this interface. You must also enable the downstream IGMP mroute proxy interfaces
on this device using the command ip igmp mroute-proxy.
IGMP Proxy does not work with other multicast routing protocols, such as PIM-SM
or PIM-DM.
From version 5.4.7-1.1 onwards, IGMP mroute proxy interfaces do not have to be
configured with an IP address before they can operate. Instead, it is possible to
have an addressless interface operate as an IGMP mroute proxy interface.
This feature is useful when IGMP Proxy needs to run on many downstream
interfaces. For example, you may want to use it if your device has one subscriber
(multicast receiver) per VLAN, and many receivers (many VLANs) connected to the
device. In such a situation, assigning IP addresses to each VLAN may not be
practicable.
Note that for such interface to be able to send queries to hosts directly attached to
the interface, it is necessary to enable IGMP snooping querier on the interface,
using the command ip igmp snooping querier.
Example To configure vlan3 as the upstream proxy-service interface for the downstream
vlan2 interface, use the commands:
awplus# configure terminal
awplus(config)# ip multicast-routing
awplus(config)# interface vlan3
awplus(config-if)# ip igmp proxy-service
awplus(config-if)# ip igmp
awplus(config)# interface vlan2
awplus(config-if)# ip igmp mroute-proxy vlan3
awplus(config-if)# ip igmp
