  Router (config-if) # ip address 202.112.7.249 255.255.255.252

  8、接口的开启与关闭

  Router (config-if) # shutdown/no shutdown

  9、不作ARP代理

  Router (config-if) # duplex ful

  l# no ip directed-broadcast

  # no ip proxy-arp

  10、配置异步串行接口

  Router (config) # interface a1

  Router (config-if) # ip unnumbered ethernet0

  Router (config-if) # encapsulation ppp

  Router (config-if) # async default ip address 202.112.7.129

  Router (config-if) # async dynamic routing

  Router (config-if) # async mode interactive

  Router (config-if) # no shutdown

  Router (config-if) # exit

  Router (config) # exit

  Router (config) #
