正确答案及解析
正确答案
解析
router（config）# ip route network [mask] {address|interface} [distance] [permanent]
[distance] [permanent]是在配置浮动静态路由的选项，在软考中不会考察。浮动静态路由是一种特殊的静态路由，通过配置一个比主路由的管理距离更大的静态路由，保证网络中主路由失效的情况下，提供备份路由。但在主路由存在的情况下它不会出现在路由表中。
{address|interface}，在静态的添加到达目的网络的路由的时候，可以指定路径中下一台设备的地址，也可以指定与下一台设备连接的自己这台路由器的接口。
