实验要求：
    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； 
    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；

# Router1
    Router>enable
    Router#configure terminal
    Router(config)#hostname R-1
    R-1(config)#interface f0/1
    R-1(config-if)#ip address 10.10.10.254 255.255.255.0
    R-1(config-if)#no shutdown
    R-1(config-if)#interface f0/0
    R-1(config-if)#ip address 10.10.20.253 255.255.255.0
    R-1(config-if)#no shutdown
    R-1(config-if)#exit
    R-1#show ip interface brief
    R-1#show ip route
    R-1#configure terminal 
    R-1(config)#ip route 10.10.30.0 255.255.255.0 10.10.20.254
    R-1(config)#ip route 10.10.40.0 255.255.255.0 10.10.20.254
    R-1(config)#exit
    R-1#show ip route 
    R-1#write

# Router2
    Router>enable
    Router#configure terminal
    Router(config)#hostname R-2
    R-2(config)#interface f0/0
    R-2(config-if)#ip address 10.10.20.254 255.255.255.0
    R-2(config-if)#no shutdown
    R-2(config-if)#interface f0/1
    R-2(config-if)#ip address 10.10.30.253 255.255.255.0
    R-2(config-if)#no shutdown 
    R-2(config-if)#exit
    R-2#show ip interface brief
    R-2#show ip route
    R-2#configure terminal
    R-2(config)#ip route 10.10.10.0 255.255.255.0 10.10.20.253
    R-2(config)#ip route 10.10.40.0 255.255.255.0 10.10.30.254
    R-2(config)#exit
    R-2#show ip route 
    R-2#write

# Router3
    Router>enable
    Router#configure terminal
    Router(config)#hostname R-3
    R-3(config)#interface f0/1
    R-3(config-if)#ip address 10.10.30.254 255.255.255.0
    R-3(config-if)#no shutdown 
    R-3(config-if)#interface f0/0
    R-3(config-if)#ip address 10.10.40.254 255.255.255.0
    R-3(config-if)#no shutdown 
    R-3(config-if)#exit
    R-3#show ip interface brief
    R-3#show ip route
    R-3#configure terminal
    R-3(config)#ip route 10.10.10.0 255.255.255.0 10.10.30.253
    R-3(config)#ip route 10.10.20.0 255.255.255.0 10.10.30.253
    R-3(config)#exit
    R-3#show ip route 
    R-3#write

2、去掉静态路由，配置默认路由使PC1与PC2能够通信；

首先，需要取消之前设置的静态路由
    # Router1
    R-1>enable
    R-1#show ip route
    R-1#configure terminal 
    R-1(config)#no ip route 10.10.30.0 255.255.255.0 10.10.20.254
    R-1(config)#no ip route 10.10.40.0 255.255.255.0 10.10.20.254
    R-1(config)#exit
    R-1#show ip route
    R-1#write
    
    # Router2
    R-2>enable
    R-2#show ip route
    R-2#configure terminal 
    R-2(config)#no ip route 10.10.10.0 255.255.255.0 10.10.20.253
    R-2(config)#no ip route 10.10.40.0 255.255.255.0 10.10.30.254
    R-2(config)#exit
    R-2#show ip route
    R-2#write
    
    # Router3
    R-3>enable
    R-3#show ip route
    R-3#configure terminal 
    R-3(config)#no ip route 10.10.10.0 255.255.255.0 10.10.30.253
    R-3(config)#no ip route 10.10.20.0 255.255.255.0 10.10.30.253
    R-3(config)#exit
    R-3#show ip route
    R-3#write

下面开始配置默认路由
    # Router1
    R-1#configure terminal 
    R-1(config)#
    R-1(config)#ip r
    R-1(config)#ip route 0.0.0.0 0.0.0.0 10.10.20.254
    R-1(config)#exit
    R-1#show ip route
    R-1#write
    
    # Router2
    R-2#configure terminal 
    R-2(config)#ip route 0.0.0.0 0.0.0.0 10.10.20.253
    R-2(config)#ip route 0.0.0.0 0.0.0.0 10.10.30.254
    R-2(config)#exit
    R-2#show ip route
    R-2#write
    
    # Router3
    R-3#configure terminal 
    R-3(config)#ip route 0.0.0.0 0.0.0.0 10.10.30.253
    R-3(config)#exit
    R-3#show ip route
    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。
