ip cef does not work
I'm running 12.1(3)XG5 and 12.2(37) on the routers.
I'm trying to add the command, "ip verify unicast reverse-path" and it tells me to enable CEF first, so it this IOS must support it
router(config-if)#ip veri u r
% CEF not enabled. Enable first
router(config)#ip cef
^
% Invalid input detected at '^' marker.
