Hi all, Thanks again, because of your help it is working fine but i have a problem with 2 compute nodes(each one is having different OVS), below is the complete scenario. [image: Inline image 1]
Here, when receiver VM1 sends IGMP v2 reports, it reaches to OVS2 also but only OVS1 is able to Snoops that but OVS2 is not able to snoop. So, Now my question is that does ovs snoops only to those ports which is connected to host? Can't it snoop the other port which is not connected to host but IGMP report is coming from there? here br-tun and br-int is bridges on ovs, i have enabled the snooping on br-int On Thu, Dec 4, 2014 at 5:30 PM, Flavio Leitner <f...@redhat.com> wrote: > On Thu, Dec 04, 2014 at 03:25:08PM +0530, Aman Kumar wrote: > > Thanks a lot guys it worked.....[?] > > Glad to hear that! > fbl > > > > > > On Wed, Dec 3, 2014 at 6:09 PM, Flavio Leitner <f...@redhat.com> wrote: > > > > > On Wed, Dec 03, 2014 at 03:16:34PM +0530, Aman Kumar wrote: > > > > > It supports only IGMPv1 and IGMPv2, so make sure the membership > > > > reports are using either one of those versions. > > > > > > > > The multicast snooping works as part of action NORMAL, so if you > > > > are steering your traffic using other flow actions, then it wouldn't > > > > work. > > > > > > > > Yes, action is NORMAL.
