思科lookback怎么配置?
和其他端口的配置一样的。它非常稳定,除非你的路由器挂掉了, 给你个例子: R1(config)#int loopback 1 %LINK-5-CHANGED: Interface Loopback1, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback1, changed state to up R1(config-if)#ip add 1.1.1.1 255.255.255.0 R1(config-if)#no shut R1(config-if)#exit
