what you've proposed. For instance, could there be a way to set multiple metadata values on a switch port and choose which to use for a particular packet based on certain criteria? Could this metadata concept be used internally as a method of implementing port group matches?

Re: [ovs-discuss] ipam allows address conflicts?

Hi Ben, Thanks for reaching out. Right now it's not obvious why big endian architecture would cause duplicate IPs to be assigned. My initial thought was that the wrong byte ordering was being used when adding IP addresses to IPAM, but it appears that host byte ordering is being used
