I just tested with ip igmp snooping on 2 VLANs:
Before setup : VAP with vlan pool of 2 vlans, DMO enabled, supress-arp enabled and supress-all disabled, on both interface vlan I've put an IP adresse and enabled local-proxy-arp. Works on both VLANs
Tested :
IGMP snooping with DMO > breaks multicast across VLANs
IGMP snooping without DMO > works across VLANs
IGMP snooping without DMO + broadcast filter-all > breaks all client discovery
IGMP snooping without DMO + bc/mc-optimization > beaks all clients discovery
IGMP proxy without DMO + broadcast filter-all > breaks all client discovery
Everyone is connecting on the wireless
I have 1 teacher laptop (sending multicast to discover student clients) connecting on vlan 1
I have 2 student clients, one connecting on vlan 1 and the other on vlan 2
Does the multicast really need to be originating from the wired side ?
