How to Configure Failover With FreeVRRPD
BSD Vault tells us how to set up
failover using FreeVRRPD.
"The basic idea is, to have two servers for one service. Every server is master (priority 255) for one virtual IP and slave for second virtual IP (priority 250). In our case, Server1 is master for 192.168.0.10 and in the same time slave for 192.168.0.11. If Server1 goes down, Server2 (slave server for IP 192.168.0.10) notice that and takes over that IP. Now Server2 has two aliases on one interface. Result: customers see's no service downtime, as takeover time is at max 3 seconds."
