I have a set of broadcasting devices that are using multicast.
Here is the configuration :
L3 SWITCH#
igmp-snooping
interface Vlan-interface280
description BroadcastDevice
ip address x.x.x.x 255.255.255.0
pim sm
igmp enable
igmp version 3
interface Vlan-interface206
description Subscribers
ip address x.x.x.x 255.255.254.0
igmp enable
igmp version 3
interface Vlan-interface226
description Not-Subscribers
ip address x.x.x.x 255.255.254.0
igmp enable
igmp version 3
I am running IGMP Snooping to make sure multicast traffic is not forwarded to every port in my network. Here is a sample from my Access Switch for the relevant vlans :
L2 ACCESS SWITCH#
igmp-snooping
vlan 206
name Subscribers
igmp-snooping enable
igmp-snooping version 3
vlan 226
name Not-Subscribers
This works well. VLAN 206 users are subscribing to the source flows from VLAN 241 and VLAN 226 are not receiving anything multicast.
I wish to filter multicast on my WIFI vlans the same way I did with the VLAN 206. Here is how I tried to do it :
L3 SWITCH#
interface Vlan-interface250
description WIFI-ADMIN
ip address x
igmp enable
igmp version 3
interface Vlan-interface252
description WIFI-SSID-CORP
ip address x
igmp enable
igmp version 3
vlan 250
igmp-snooping enable
igmp-snooping version 3
vlan 252
igmp-snooping enable
igmp-snooping version 3
VLAN 250 is the vlan in which my clients are located when they authenticate on the controller. VLAN 252 is the controller VLAN.
With this configuration, my WIFI clients are still able to subscribe to multicast flows, which then brings my WiFi network down.
Anyone has any tips on what I am missing here ? Should I look in the controller configuration directly? It's a HP MSM 760.
Thank you
