Proxy Interface
The purpose of IGMP Proxy is to enable a multicast router to learn multicast group membership
information and be able to forward multicast packets based upon the group membership information.
The IGMP Proxy is capable of functioning only in certain topologies that do not require Multicast
Routing Protocols (i.e. DVMRP, PIM-DM, and PIM-SM) and that have a tree-like topology, as there is no
support for features like spanning tree to correct packet route loops.
The Proxy In terface menu page contains links to web pages that define and display Proxy Interface
parameters and data. To display this page, click IP Multicast > IGMP > Proxy Interf ace in the tree
view. Following are the web pages accessible from this menu page:
• IGMP Proxy Interface Configuration
• IGMP Proxy Configuration Summary

IGMP Proxy Interface Configuration
The IGMP Proxy is used by IGMP Router (IPv4 system) to enable the system to issue IGMP host
messages on behalf of hosts that the system discovered through standard IGMP router interfaces. Thus,
this feature acts as proxy to all hosts residing on its router interfaces.
Use the IGMP Proxy Interface Configuration
page to configure IGMP proxy for an interface. You must
have configured at least one router interface before configuring or displaying data for an IGMP proxy
interface, and it should not be an IGMP routing interface.
To display the page, click IP Multicast > IGMP > Proxy In terfac e > Interface Configuration in the
tree view.
