Cisco IGMP Configuration Example
In this configuration example, we will configure Cisco Catalyst Switch for IGMP (Internet Group Management Protocol). As you know IGMP is used to manage host memberships to the multicast groups. This is done at the edge switch in the multicast network. So, we will do our configuration on this edge switch.
For our IGMP Configuration Example, we will use the below Multicast topology:
Here, we will do IGMP Configuration on Cisco Catalyst switch for the below jobs:
• Switch Multicast Group membership
• Changing IGMP version
• Configuring IGMP timers
Let’s start to configure our Catalyst Switch for IGMPv3.
Switch Multicast Group membership
Firstly, we will configure our Switch A as a member of different Multicast Groups. Here, we will use the groups, 18.104.22.168 and 22.214.171.124. To do this, we will use “ip igmp join-group group-address” command.
By the way, there are two methods to pull the Multicast traffic to the switch. These methods can be used with below commands :
• ip igmp join-group group-name
• ip igmp static-group group-name
