Not sleeping for two days straight, and for leaving Hot FM Big Jam, finally CCNA exam has been finished. Really stressful this few days. I don't quite study for my exam instead of playing dota + karaoke. Haha, what an awful combination. Luckily, I can solve all the skill-based test. Inter-Vlan is not that hard. Learned a few command for router and addition two command in switching. The basis of inter-Vlan is to have a router on switched lan, some called it 'router-on-stick'. Since switch is basically level 2 devices, it cannot forward packet into different subnetwork. Unless we have level 3 switch. Here is a big picture of inter-vlan routing that I have solved. Got a little confident to win my cisco network competition at the end of this March.
