Configuring Igmpv3 Explicit Host Tracking - Cisco 7604 Configuration Manual

Chapter 30 Configuring IGMP Snooping for IPv4 Multicast Traffic
Enabling SSM Safe Reporting
Source-specific multicast (SSM) safe reporting is deprecated in Release 12.2(18)SXE and later releases.
Note
When you configure SSM safe reporting, the group mode is IGMPv3 even in the presence of IGMPv1
and IGMPv2 hosts.
To make sure the router is able to support both IGMPv1, IGMPv2, and IGMPv3 hosts in the same VLAN,
perform this task:
Command
Step 1
Router(config)# interface vlan vlan_ID
Step 2
Router(config-if)# ip igmp snooping
ssm-safe-reporting
Router(config-if)# no ip igmp snooping
ssm-safe-reporting
This example shows how to configure the router to support both IGMPv2 and IGMPv3 hosts:
Router(config)# interface vlan 10
Router(config-if)# ip igmp snooping ssm-safe-reporting

Configuring IGMPv3 Explicit Host Tracking

To enable explicit host tracking on a VLAN, perform this task:
Command
Step 1
Router(config)# interface vlan vlan_ID
Step 2
Router(config-if)# ip igmp snooping
explicit-tracking
Router(config-if)# no ip igmp snooping
explicit-tracking
Step 3
Router# show ip igmp snooping explicit-tracking
{vlan vlan-id }
This example shows how to enable explicit host tracking:
Router(config)# interface vlan 25
Router(config-if)# ip igmp snooping explicit-tracking
Router(config-if)# end
Router# show ip igmp snooping explicit-tracking vlan 25
