What is IGMP :

Internet Group Management Protocol (IGMP) is a protocol that allows IP routers to dynamically determine which multicast groups have clients in a subnet.

IGMP is a protocol executed between the host machines of the same subnet and the multicast routers of this subnet. It allows a host machine to inform one of these multicast routers about its current subscriptions to multicast groups. Routers maintain the list of multicast groups to which host machines have reported that they are subscribed.

IGMP SNOOPING

IGMP Snooping controls these multicast groups by monitoring and analyzing multicast packets exchanged between upstream Layer 3 multicast devices and downstream hosts to suppress unnecessary multicast data transfer in multicast networks. layer 2.

it’s better to use a Vlan dedicated for IGMP (here VLAN 10)

Master Switch side :

Enable IGMP Snooping

Advanced Configuration / IGMP Snooping

VLAN Configuration:

Add new IGMP VLAN (example here VLAN 10)

Tag Settings :

command-line :

vlan 10

name VLAN10

fixed 1-10

tagged 1-10

no snmp_v1v2c server

no snmp_v3 server

igmp-snooping vlan 10

igmp-snooping enable

igmp-snooping querier vlan 10

igmp-snooping querier enable
