Message-ID: <CAF1ivSbGo20rUdRa3tEDv+v8iDWpdH+1e-vunLx4oC+4iwSASw@mail.gmail.com> Date: Tue, 25 Sep 2012 10:59:08 +0800 From: Lin Ming <mlin@...pku.edu.cn> To: Herbert Xu <herbert@...dor.apana.org.au> Cc: networking <netdev@...r.kernel.org> Subject: IGMP snooping problem Hi, I'm testing IGMP snooping on a router which has 4 LAN ports. # brctl show bridge name bridge id STP enabled interfaces br0 8000.00037fbef050 yes eth0 eth1 eth2 eth3 ath0 ath1 ath2 ath3 ath0, 1, 2, 3 are WIFI. IGMP snooping works well with this configuration. The router supports a "switch mode", namely the 4 LAN ports connected to a on-board switch. In this mode, there is only a eth0, no eth1,2,3. One benefit of this mode is that the traffic between LAN ports don't need to go to CPU. The LAN ports traffic will be handled by hardware switch directly. # brctl show bridge name bridge id STP enabled interfaces br0 8000.00037fbef050 yes eth0 ath0 ath1 ath2 ath3 In this mode, the IGMP snooping among the 4 LAN ports won't work. Any idea how to resolve this problem?
