Dear all,
I know that ML2 Neutron core plugin is designed to support multiple mechanism and type drivers simultaneously. But I'd like to know: is it possible to use the same network interface configured with different ML2 mechanism drivers?
I'm planning to use openvswitch and linuxbridge as mechanism drivers along with VLAN as type driver. Could it be possible to have the following configuration for that purpose?:
ml2_conf.ini: [ml2] mechanism_drivers = openvswitch,linuxbridge [ml2_type_vlan] network_vlan_ranges = physnet1:40:60,physnet2:60:80
eth3 is a port of the provider bridge: ovs-vsctl add-port br-provider eth3
openvswitch_agent.ini: [ovs] bridge_mappings = physnet1:br-provider
linuxbridge_agent.ini: [linux_bridge] physical_interface_mappings = physnet2:eth3
I don't think it's will work because You would need to have same interface in the ovs bridge (br-provider) and use it by linuxbridge. But TBH this is a bit strange configuration for me. I can imaging different computes which are using different backends. But why You want to use linuxbridge and openvswitch agents together on same compute node?
If it's mandatory to use different network interfaces any guide or sample reference about implementing multiple mechanism drivers would be highly appreciated.
Thanks in advance, Gabriel Gamero
