For my own understanding, is it fair to assume: - "no ip route-cache" forces punting to the RP for proc-switch - lack of "no ip route-cache" and without "ip cef" enabled (at all) implies 'proc-switch once, then fast-switch' - nothing explicitly set on an interface, but "ip cef" enabled globally will always use the compiled FIB ...do I have this right?
