How can I really get a really good unserstanding of Cisco material. I am trying so hard. I seem to be spinning my wheels and I keep reading and it seems to go in one ear and out the other. It is not that I am not interested. I am. I just don't seem to be able to configure a router for real no matter what I read. I looked into a school but they wanted thousands of dollars. That is steep for me now. The desire is there but I get discouraged because I really want to know what I am doing. Thanks.
