CISCO路由器实现双线接入

CISCO实现双线接入   第一步：  配置cnc接口：  interface GigabitEthernet5/1  ip address 60.10.135.11 255.255.255.224  ip nat outside 配置tel接口：  interface GigabitEthernet5/9  ip address 219.148.157.22 255.255.255.252  ip nat outside 配置内网接口：  interface GigabitEthernet5/2  ip address 192.168.0.1 255.255.255.0  ip nat inside 第二步：配置accelist-list access-list 100 permit ip 192.168.0.0 0.0.0.255 any 第三步：分别配置cnc和tel的地址池  ip nat pool pool2 60.10.135.11 60.10.135.11 netmask 255.255.255.224  ip nat pool pool1 219.148.157.22 219.148.157.22 netmask 255.255.255.252 第四步：配置两个route-map route-map isp2 permit 10  match ip address 100  match interface GigabitEthernet5/1  !  route-map isp1 permit 10  match ip address 100  match interface GigabitEthernet5/9 第五步：配置两个nat ip nat inside source route-map isp1 pool pool1 overload  ip nat inside source route-map isp2 pool pool2 overload 第六步：配置路由  缺省从电信走：ip route 0.0.0.0 0.0.0.0 219.148.157.21  目的地址是网通的走网通，例如:ip route 202.99.168.0 255.255.248.0 60.10.135.1  将全国的网通地址段全部添加上即可完成。
