IGMP querying router is 192.168.1.1 (this system) Multicast designated router (DR) is 192.168.1.1 (this system) Multicast routing is enabled on interface

Last member query response interval is 1000 ms IGMP max query response time is 10 seconds IGMP configured querier timeout is 120 seconds IGMP configured query interval is 60 seconds GigabitEthernet0/1 is up, line protocol is upĬurrent IGMP router version is 2 IGMP query interval is 60 seconds We can verify that it’s running: R1# show ip igmp interface GigabitEthernet 0/1 R1(config)# interface GigabitEthernet 0/1įirst we have to enable multicast routing and PIM on the interface otherwise the router won’t process IGMP traffic. Let’s start with R1: R1(config)# ip multicast-routing To demonstrate these new features, I’ll use the following topology:Ībove we have one multicast-enabled router and two hosts. The router with the lowest IP address becomes the active querier.

Querier election process: when there are two routers in the same subnet then only one of them should send query messages. The election ensures only one router becomes the active querier.

I will explain later why we use this with an example. It specifies how much time hosts have to respond to the query.

MRT (Maximum Response Time) field: this is a new field in query messages.

When the router receives a leave group message, it will use this query to check if there are still any hosts interested in receiving the multicast traffic.

Group specific membership query: the router is now able to send a membership query for a specific group address.

Leave group messages: when a host no longer wants to listen to a multicast group address then it will report to the router that it has stopped listening.

In IGMP version 1, hosts just stop listening to the multicast group address but they never report this to the router. One of the major reasons for a new version was to improve the “leave” mechanism. IGMP version 2 is the “enhanced” version of IGMP version 1.
