Adding the IP Failover on FreeBSD

  • 772

I've just bought a dedicated server in OVH.com and they are sending me some warnings in email that I haven't configured my IP Failover address correctly and they're going to block this failover within 24 hours if I won't take any actions.

So, the question is, how should IP Failover be configured properly in FreeBSD 8.2?

    Have a look at lagg(4) (FreeBSD Handbook entry). The ifconfig commands you need are:

    ifconfig em0 up
ifconfig em1 up
ifconfig lagg0 laggproto failover laggport em0 laggport em1 192.168.1.1 netmask 255.255.255.0

    (Substitute em0, em1, IP address and netmask as appropriate.)

    The equivalent for rc.conf is:

    ifconfig_em0="up"
ifconfig_em1="up"
cloned_interfaces="lagg0"
ifconfig_lagg0="laggproto failover laggport em0 laggport em1 192.168.1.1 netmask 255.255.255.0"
