Did you go through the Cisco Doc configuration guides for every topic? Should I do lab exercises for every topic or just find out how the technology and the respective command works? Up to know I try every command encountered in the books and try different topologies. I make sure I understand everything and if something is unclear or if I cannot find it anywhere on the net, I just lab it out. Thanks in advance!
