IP classless command [7:30056]

2001-12-24 Thread Hunt Lee

Hello Mike. thanks so much for your detailed explanation. However, I'm still confused about how the ip classless works. I understand that "classful" rules (if no ip classless is configured), with the 10.1.1.0/24 static route, it would forward anything from 10.1.1.1 to 10.1.1.254, but why would
