Mikrotik RouterOS with Failover IP

19-10-2014, 00:51
Just a quick guide on howto get connectivity with your failover IP in Mikrotik RouterOS.

Install RouterOS and on first boot press `r` to reject the default configuration.

1) Add your failover IP to the interface

ip address add address=FAILOVER_IP/32 broadcast=FAILOVER_IP
2) Add your failover IP again but this time - you need to add your Hosts gateway IP as the network parameter.

ip address add address=FAILOVER_IP/32 network=HOST_GWIP broadcast=FAILOVER_IP
3) Add the default route

ip route add dst-address= gateway=HOST_GWIP
4) Confirm connectivity
