I'm in a debate with a guy over the use of 'ip address x.x.x.x s.s.s.s secondary' on Cisco gear. I seem to remember reading that the use of secondary addresses is a bad idea, but I can't recall the details of why. Process switched?
No, traffic to hosts within a subnet configured as secondaries will be CEF switched. The only "bad" thing I can think of with secondaries, is that it's often not what you want, why not split it on layer 2 as well, and get the benefit of a smaller broadcast domain ?
Can anyone offer a resource or more specific information?
