Thanks for the answer Dan, Now I know everything I need. On Fri, Aug 24, 2012 at 10:32 PM, Dan Wendlandt d...@nicira.com wrote: Hi Juris, Some more detail would be useful here. It sounds like you're trying to use multicast, for which IGMP is a control protocol. Is it that you're trying to run nova VMs and make sure they can participate in multicast groups? Basic flat Nova networking connects VMs directly to a physical network, so the configuration of multicast on the routers (and IGMP snooping on the switches) is generally something that would happen outside the scope of openstack configuration. For private networks in VlanManager mode or with Quantum, the existing L3 forwarding logic does not run a daemon that participates in IGMP, so there's no out-of-the box way to get IGMP working between a private network and the external network in your data center, I suspect (my guess is that you'd have to muck with making the host running nova-network or the quantum-l3-agent also run a multi-cast aware routing software, like Quagga). In the future, Quantum will enable pluggable back-ends for logical routers, in which case you'll be able to get routing back-ends from different vendors and projects, many of which will support IGMP.

[Openstack] OpenStack and IGMP
Hi all, Do you have any experience configuring OpenStack to work with IGMP traffic? If I have IGMP server and appropriate network infrastructure, what is the best way to bound it with one of OpenStack's private networks? ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
