静态路由协议
静态路由是指由网络管理员手工配置的路由信息，而非动态决定。与动态路由不同，静态路由是固定的，不会改变，即使网络状况已经改变。静态路由除了具有简单、高效、可靠的优点外，它的另一个好处是网络安全保密性高。缺省路由可以看做是静态路由的一种特殊情况。当数据在查找路由表时，没有找到和目标相匹配的路由表项时，为数据指定路由。
配置命令
ip route 192.168.2.0 255.255.255.0 192.168.3.2 //目的网络号子网掩码 出口下一跳
ip route 192.168.2.0 255.255.255.0 se2/0 //目的网络号子网掩码 出接口
ip route 0.0.0.0 0.0.0.0 192.168.1.1 //缺省路由配置实例
