Hello folks: Currently, we can build up a connection between two VxLAN networks by setting unicast ip address to the "remote_ip" option of VxLAN type interface on openvswitch. But when there are many VxLAN networks, we hope to broadcast the VxLAN packet to all peers; but it is in-convenient to set all the unicast "remote_ip" parameters one-by-one. I have tried to set the "remote_ip" with a multicast group address, such as 224.0.0.2 or 225.1.1.1 using command: sudo ovs-vsctl add-port br1 vx1 -- set interface vx1 type=vxlan options:remote_ip=225.1.1.1 The command does not return error, but ovs does not send the multicast VxLAN packet out as expected. And in log, I can find a warning "vx1: multicast remote_ip=225.1.1.1 not allowed". Originally, VxLAN depends on multicast to find & resolve the Mapping(IP, MAC) among different VxLAN networks. So I think there might be some kind of configure to make use of the multicast characteristic of VxLAN.
Can you kindly offer me some help on it? I would really appreciate your help. Thanks!
