Ever used HSRP / VRRP?  Two interfaces in the same subnet.  Works
fine.  In fact, most people think it works _better_ than one
interface
in the same subnet.

I guess you are mixing interfaces with IPs now. Don't you?

Each interface has its own IP address.  The two Interfaces _also_
share a virtual IP address.

IOW: No.  Are you?


But still each device only has _one_ interface in the same subnet.
Though with two IP addresses sometimes.

Of course, was thinking about using it on the same router. But I guess that doesn't work so well, does it? :)
