Hi all,
I have an openstack setup using ml2/ovs/vxlan. While sending multicast
traffic on one VM, I am seeing packets being replicated to many
hypervisors via VXLAN tunnels, although I only have a couple of
receiver VMs on a couple of hypervisors. Is this expected?
I set mcast_snooping_enable=true for br-int and br-tun bridges.
Haven't looked into this part of OVS in detail, I am wondering if OVS
can "learn" where the receivers are and therefore do not replicate
multicast packets everywhere.
Thanks.
