[Liufei]ospf enable ；启动OSPF协议 [Liufei-ospf]import-route direct ；引入直联路由 [Liufei-Serial0]ospf enable area ；配置OSPF区域 标准访问列表命令格式如下： acl [match-order config|auto] ；默认前者顺序匹配。 rule [normal|special]{permit|deny} [source source-addr source-wildcard|any] 例： [Liufei]acl 10 [Liufei-acl-10]rule normal permit source 10.0.0.0 0.0.0.255 [Liufei-acl-10]rule normal deny source any 扩展访问控制列表配置命令 配置TCP/UDP协议的扩展访问列表： rule {normal|special}{permit|deny}{tcp|udp}source {|any}destination |any} [operate] 配置ICMP协议的扩展访问列表： rule {normal|special}{permit|deny}icmp source {|any]destination {|any] [icmp-code] [logging] 扩展访问控制列表操作符的含义 equal portnumber ；等于 greater-than portnumber ；大于 less-than portnumber ；小于 not-equal portnumber ；不等 range portnumber1 portnumber2 ；区间 扩展访问控制列表举例 [Liufei]acl
