Subject:   LAN failover redundandcy?

Hi,

I'm looking for a way to configure failover redundancy for one of my
servers. To be specific:

The server in question has one IP-address but two LAN interfaces each
of them connecting to a different switch. 

Traffic normally runs only through one of the two interfaces; the
other is for redundandy only. In case the active LAN-interface goes
down (e.g. because of a link and/or switch failure) the second
LAN-interface should take over in the sense that traffic should run
through the second interface (again the server has only one
IP-address, so binding a different IP-address to the interface is not
an option here)

Is there any way how this can be configured under FreeBSD 6.2?

Thanks much in advance for your help,
-ewald
