思科雙線路接入方案

  (一地址配置)

  r1(config)#int f0/0

  r1(config-if)#ip add 61.153.177.1 255.255.255.0

  r1(config-if)#no shut

  %LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

  r1(config-if)#int f0/1

  r1(config-if)#ip add 192.168.1.1 255.255.255.0

  r1(config-if)#no shut

  r1(config)#int s1/0

  r1(config-if)#ip add 112.55.33.1 255.255.255.0

  r1(config-if)#no shut

  電信r1(config)#ip route 0.0.0.0 0.0.0.0 61.153.177.3

  網通r1(config)#ip route 113.55.33.0 255.255.255.0 112.55.33.11

  r1(config)#ip route 114.55.33.0 255.255.255.0 112.55.33.11

  二(NAT配置)

  r1(config)#int f0/0

  r1(config-if)#ip nat outside

  r1(config-if)#exi

  r1(config)#int s1/0

  r1(config-if)#ip nat outside

  r1(config-if)#end

  NAT地址池

  r1(config)#ip nat pool wt 112.55.33.5 112.55.33.5 netmask 255.255.255.0

  r1(config)#ip nat pool dx 61.153.177.2 61.153.177.2 netmask 255.255.255.0

  配置兩個route map

  Route-map isp2 permit 10

  Match ip address 100

  Match int s1/0

  Route-map isp1 permit 10

  Match ip address 100

        Match int f0/0
