Using IGMP but Multicast still Flooding

Question

Im new here.

I want to ask about the multicast,

The first case is, I have switch HP 2530 24 port with 24 10/100 and 2 100/1000 NIC, And i have servers with bandwidth video multicast around 120-125Mbps. Servers plug into 2 gigabit NIC switch and the client into 10/100 NIC. Using IGMPv2 as the default.

The problem is,

1. When I set IGMP to mode AUTO the video is good and multicast not flooding to the client. But after 5-10 minutes the client stop receive multicast traffic.

2. And I set IGMP to mode FORWARD, Client receive multicast trafiic and video NOT stopping after 5-10 minutes. But the problem is the client only have 10/100 NIC but multicast traffic send bandwidth around 120mbps, so when i start playing video, The video is Lagging.

Any suggestion guys? maybe have a sollution for this problem?

Thanks.

This is my igmp config

Answer 1

You need to configure the 2530 for IGMP forwarding, otherwise it'll simply flood.

For instance,

vlan 1 ip igmp

turns on IGMP forwarding for VLAN 1 and sets the switch querier to automatic mode.

Additionally, you can use the vlan x ip igmp options to disable all but one switch as querier - there must be one querier for each cast - and to limit IGMP casts to specific addresses.

EDIT: what you call config is a show ip igmp output. It does however give several hints.

Querier Address : Querier initial wait

indicates a problem with the querier - no querier, no multicast. For the switch to work as querier it requires an IP address for the VLAN.
