Turn off "primary" Kea DHCP server, "standby" server Overview This repository contains the configuration for a Kea DHCPv4 server with advanced features, including High Availability (HA) in a hot-standby mode. The Kea HA hook works by pairing Kea servers in either an active-active or active A KEA DHCP cluster configured for the hot-standby mode will have the primary node serving DHCP clients and another node only receiving the lease-database updates, but A modern, scalable, robust DHCPv4 and DHCPv6 server. To Reproduce Steps to reproduce the behavior: Enable Kea DHCP and set up HA. ISC Kea DHCP HA Failover I am migrating from dhcpd to Kea and setting up a simple HA hot-standby pair.

The hooks This was tested a few times. FreeBSD presents a slight Hot standby In this configuration, one of the servers is designated as primary and another as secondary. When I take down If any of the secondary/standby/backup servers are offline, replication to all other servers will still take place but Micetro will report the Kea DHCP service Impaired.
