Support active-active and active-passive high availability modes in DHCP server
Closed, ResolvedPublicFEATURE REQUEST

Description

We currently have the need to run our DHCP servers in hotspare mode, meaning the primary is the only dhcp server until it fails, at which point the secondary gets the entire pool.

Currently we've implemented this on equuleus by manually changing split 128; to split 256; in /usr/share/vyos/templates/dhcp-server/dhcpd.conf.tmpl

Obviously with the change to Kea dhcpd this won't work anymore - any chance of a config option to make this happen?
