  • Layer-3 (native OVN implementation or conventional layer-3 agent)The native OVN implementation supports distributed routing. However,it currently lacks support for floating IP addresses, NAT, and themetadata proxy.

  • DHCP (native OVN implementation or conventional DHCP agent)The native implementation supports distributed DHCP. However,it currently lacks support for IPv6, internal DNS, and metadataproxy.
