Configuring IGMP SSM mappings

This feature enables the device to provide SSM services for IGMPv1 or IGMPv2 hosts.
This feature does not process IGMPv3 messages. As a best practice, enable IGMPv3 on the
receiver-side interface to avoid IGMPv3 hosts failing to join multicast groups.

Configuration prerequisites

Before you configure IGMP SSM mappings, complete the following tasks:
•
Configure any unicast routing protocol so that all devices in the domain can interoperate at the
network layer.
•
Configure basic IGMP features.

Configuration procedure

To configure an IGMP SSM mapping:
Step
1. Enter system view.
2. Enter IGMP view.
3. Configure
SSM mapping.

Configuring IGMP proxying

This section describes how to configure IGMP proxying.
Configuration prerequisites
Before you configure the IGMP proxying feature, complete the following tasks:
1. Configure a unicast routing protocol so that all devices in the domain can interoperate at the
network layer.
2. Determine the router interfaces and host interfaces based on the network topology.
3. Enable IGMP on the router interfaces.

Enabling IGMP proxying

When you enable IGMP proxying, follow these restrictions and guidelines:
•
You must enable IGMP proxying on the receiver-side interfaces.
•
On an interface enabled with IGMP proxying, only the igmp version command takes effect and
other IGMP commands do not take effect.
•
If you enable both IGMP proxying and a multicast routing protocol (such as PIM or MSDP) on
the same device, the multicast routing protocol does not take effect.
In IGMPv1, the DR is elected by PIM and acts as the IGMP querier. Because PIM does not take
effect on a proxy device, a router interface running IGMPv1 cannot be elected as the DR. To
