  1. 实验要求：
  2. 1、PC1在LAN1中，PC2在LAN2中，配置静态路由实现两个LAN中的PC能够通信； 
  3. 2、去掉静态路由，配置默认路由使PC1与PC2能够通信；

1、PC1在LAN1中，PC2在LAN2中，配置静态路由实现两个LAN中的PC能够通信；

  1. # Router1
  2. Router>enable
  3. Router#configure terminal
  4. Router(config)#hostname R-1
  5. R-1(config)#interface f0/1
  6. R-1(config-if)#ip address 10.10.10.254 255.255.255.0
  7. R-1(config-if)#no shutdown
  8. R-1(config-if)#interface f0/0
  9. R-1(config-if)#ip address 10.10.20.253 255.255.255.0
  10. R-1(config-if)#no shutdown
  11. R-1(config-if)#exit
  12. R-1#show ip interface brief
  13. R-1#show ip route
  14. R-1#configure terminal 
  15. R-1(config)#ip route 10.10.30.0 255.255.255.0 10.10.20.254
  16. R-1(config)#ip route 10.10.40.0 255.255.255.0 10.10.20.254
  17. R-1(config)#exit
  18. R-1#show ip route 
  19. R-1#write
  21. # Router2
  22. Router>enable
  23. Router#configure terminal
  24. Router(config)#hostname R-2
  25. R-2(config)#interface f0/0
  26. R-2(config-if)#ip address 10.10.20.254 255.255.255.0
  27. R-2(config-if)#no shutdown
  28. R-2(config-if)#interface f0/1
  29. R-2(config-if)#ip address 10.10.30.253 255.255.255.0
  30. R-2(config-if)#no shutdown 
  31. R-2(config-if)#exit
  32. R-2#show ip interface brief
  33. R-2#show ip route
  34. R-2#configure terminal
  35. R-2(config)#ip route 10.10.10.0 255.255.255.0 10.10.20.253
  36. R-2(config)#ip route 10.10.40.0 255.255.255.0 10.10.30.254
  37. R-2(config)#exit
  38. R-2#show ip route 
  39. R-2#write
  41. # Router3
  42. Router>enable
  43. Router#configure terminal
  44. Router(config)#hostname R-3
  45. R-3(config)#interface f0/1
  46. R-3(config-if)#ip address 10.10.30.254 255.255.255.0
  47. R-3(config-if)#no shutdown 
  48. R-3(config-if)#interface f0/0
  49. R-3(config-if)#ip address 10.10.40.254 255.255.255.0
  50. R-3(config-if)#no shutdown 
  51. R-3(config-if)#exit
  52. R-3#show ip interface brief
  53. R-3#show ip route
  54. R-3#configure terminal
  55. R-3(config)#ip route 10.10.10.0 255.255.255.0 10.10.30.253
  56. R-3(config)#ip route 10.10.20.0 255.255.255.0 10.10.30.253
  57. R-3(config)#exit
  58. R-3#show ip route 
  59. R-3#write

2、去掉静态路由，配置默认路由使PC1与PC2能够通信； 

  1. 首先，需要取消之前设置的静态路由
  2. # Router1
  3. R-1>enable
  4. R-1#show ip route
  5. R-1#configure terminal 
  6. R-1(config)#no ip route 10.10.30.0 255.255.255.0 10.10.20.254
  7. R-1(config)#no ip route 10.10.40.0 255.255.255.0 10.10.20.254
  8. R-1(config)#exit
  9. R-1#show ip route
  10. R-1#write
  12. # Router2
  13. R-2>enable
  14. R-2#show ip route
  15. R-2#configure terminal 
  16. R-2(config)#no ip route 10.10.10.0 255.255.255.0 10.10.20.253
  17. R-2(config)#no ip route 10.10.40.0 255.255.255.0 10.10.30.254
  18. R-2(config)#exit
  19. R-2#show ip route
  20. R-2#write
  22. # Router3
  23. R-3>enable
  24. R-3#show ip route
  25. R-3#configure terminal 
  26. R-3(config)#no ip route 10.10.10.0 255.255.255.0 10.10.30.253
  27. R-3(config)#no ip route 10.10.20.0 255.255.255.0 10.10.30.253
  28. R-3(config)#exit
  29. R-3#show ip route
  30. R-3#write
  32. 下面开始配置默认路由
  33. # Router1
  34. R-1#configure terminal 
  35. R-1(config)#
  36. R-1(config)#ip r
  37. R-1(config)#ip route 0.0.0.0 0.0.0.0 10.10.20.254
  38. R-1(config)#exit
  39. R-1#show ip route
  40. R-1#write
  42. # Router2
  43. R-2#configure terminal 
  44. R-2(config)#ip route 0.0.0.0 0.0.0.0 10.10.20.253
  45. R-2(config)#ip route 0.0.0.0 0.0.0.0 10.10.30.254
  46. R-2(config)#exit
  47. R-2#show ip route
  48. R-2#write
  50. # Router3
  51. R-3#configure terminal 
  52. R-3(config)#ip route 0.0.0.0 0.0.0.0 10.10.30.253
  53. R-3(config)#exit
  54. R-3#show ip route
  55. R-3#write

pc1、pc2 设置好ip、子网掩码、网关后，进行相应测试，这里就不一一列举出来了。
