  1. 静态路由 Stub Network 192.168.10.0 SO Network A B B 172.16.2.2 172.16.2.1 • 无开销，配置简单，需人工维护，适合简单拓扑结构的网络。

  2. 静态路由的例子 Stub Network 192.168.10.0 SO Network A B B 172.16.2.2 172.16.2.1 ip route 192.168.10.0 255.255.255.0 172.16.2.1 • 这是一条单方向的路径，必须配置一条相反的路径。

  3. 缺省路由 Stub Network 192.168.10.0 SO Network A B B 172.16.2.2 172.16.2.1 ip route 0.0.0.0 0.0.0.0 172.16.2.2 • 使用缺省路由后，Stub Network可以到达路由器A以外的网络。

  4. //不用于动态地址分配的地址 • ip dhcp excluded-address 192.168.10.1 192.168.10.20 • //global是pool name， 由用户指定 • ip dhcp pool a7a • //动态分配的地址段 • network 192.168.10.0 255.255.255.0 • //为客户机配置dns服务器 • dns-server 192.168.10.2 192.168.10.3 • //为客户机配置网关 • default-router 192.168.10.1

  5. 定义访问控制列表。 • access-list 1 permit 192.168.10.0 0.0.0.255

  6. 实现外接口地址的复用及IP地址的动态转换。 • ip nat inside source list 1 interface fastethernet0/1 overlocad • inside source list 1 : 表示从inside 接口进入并符合acces-list 1 要求的数据包，它的源地址将被进行PAT转换。

  7. 实现外接口地址的复用及IP地址的动态转换。 • ip nat inside source list 1 interface fastethernet0/1 overlocad • interface fastethenet0/1：表示在f0/1接口上进行接口复用。 • overload：它的意思为过载，正因为配置了overload,才能实现接口复用

  8. 在接口上启用PAT. • （config）# interface fastethent0/0 • （config-if）#ip nat inside • （config）# interface fastethent0/1 • （config-if）# ip nat outside
