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
