Because the study of the major is computer network technology, but in school, and did not learn how much network knowledge, so in order to be worthy of the professional, in 06, when working in the Galaxy education in hit a CCNA class, two weeks of the course, a few hours a day.The result is still not learned, because there is too much theory, too little real exercise.So I bought a book, repeatedly see, the theoretical things finally understand, the fo

CCNA path-1-static route ConfigurationDuring the preparation of CCNA, the route is always in disorder. Therefore, keep your daily study notes recorded for future viewing. There are two types of Static Routing configurations: one is Static Routing with the next hop address, and the other is Static Routing with the output interface. For static routing, the usage is as follows: 1. The network only contains sev
