Yeah have tried this too. We don’t do this due to metadata, DHCP adds a static route to the metadata agent (which is the same as the network node running DHCP). If the network node is down the instances loose metadata if they happened to get a lease from that DHCP server. With failover the IP address transfers to the other network node and metadata keeps working for all. Make sense? Sam
