Igmp Snooping Querier Configuration Example - HP MSR1002-4 Configuration Manual

VLAN 100: Total 1 entries.
(0.0.0.0, 224.1.1.1)
Host slots (0 in total):
Host ports (2 in total):
GE1/0/3
GE1/0/5
The output shows that GigabitEthernet 1/0/3 and GigabitEthernet 1/0/5 on Switch C have become
static member ports of multicast group 224.1.1.1.

IGMP snooping querier configuration example

Network requirements
As shown in
•
The network is a Layer 2-only network.
•
Source 1 and Source 2 send multicast data to multicast groups 224.1.1.1 and 225.1.1.1,
respectively.
•
Host A and Host C are receivers of multicast group 224.1.1.1, and Host B and Host D are
receivers of multicast group 225.1.1.1.
•
All host receivers run IGMPv2, and all switches run IGMPv2 snooping. Switch A (which is close
to the multicast sources) acts as the IGMP snooping querier.
Configure the switches to meet the following requirements:
•
To prevent the switches from flooding unknown data in the VLAN, enable all the switches to
drop unknown multicast data.
•
A switch does not mark a port that receives an IGMP query with source IP address 0.0.0.0 as a
dynamic router port. This adversely affects the establishment of Layer 2 forwarding entries and
multicast traffic forwarding. To avoid this, configure the source IP address of IGMP queries as a
non-zero IP address.
