I have following network topology and need failover for a server with two NIC's. From what I've read on the net I think I need the active-backup mode and use arp instead of mii.
So I would pass the following options :
mode=1 arp_interval=60 arp_ip_target=x.x.x.2,x.x.x.3 primary=eth1
The problem is this host is already in production so I cannot play much with the different options.
Has anyone more experience with this kind of setup and/or are my conclusions correct?
