28.11 IGMP Proxy Configuration
28.11.1 Introduction to IGMP Proxy
IGMP/MLD proxy which is introduced in rfc4605, is a simplified multicast protocol running at
edge boxes. The edge boxes which runs the IGMP/MLD proxy protocol, does not need to run
complicated multicast routing protocols such as PIM/DVMRP. However they work with
multicast protocol enabled network through IGMP/MLD proxy. They can simplify the
implementation of multicasting on edge devices.
The IGMP/MLD proxy works between the multicast router and the client, it works as both the
multicast host and router. Upstream and downstream ports should be specified in the
IGMP/MLD proxy configuration. The host protocol runs at upstream ports, while the router
protocol runs at downstream ports. The switch collects the join and leave messages received
from downstream ports and forward them to the multicast router through upstream ports.
The IGMP proxy configuration is exclusive with PIM and DVMRP configuration.
28.11.2 IGMP Proxy Configuration Task List
Enable IGMP Proxy function
Enable configurations for both downstream and upstream ports for the IGMP Proxy in different
interfaces
Configure IGMP Proxy
1. Enable IGMP Proxy function
Command
Explanation
Global Mode
ip igmp proxy
no ip igmp proxy
Enable IGMP Proxy function. The “no ip igmp
proxy” disables this function.
2. Enable configurations for both downstream and upstream ports for the IGMP Proxy in
different interfaces
Command
Explanation
Interface Configuration Mode
ip igmp proxy upstream
no ip igmp proxy upstream
Enable IGMP Proxy upstream function. The “no ip
igmp proxy upstream” disables this function.
ip igmp proxy downstream
no ip igmp proxy downstream
Enable IGMP Proxy downstream function. The
“no ip igmp proxy downstream” disables this
