Switch>enable
    
    Switch#configure terminal
    
    Switch(config)#hostname switch1
    
    switch1(config)#vlan 10
    
    switch1(config-vlan)#exit
    
    switch1(config)#vlan 20
    
    switch1(config-vlan)#exit
    
    switch1(config)#interface fa0/1
    
    switch1(config-if)#switchport access vlan 10
    
    switch1(config-if)#exit
    
    switch1(config)#interface fa0/2
    
    switch1(config-if)#switchport access vlan 10

    switch1(config-if)#exit
    
    switch1(config)#ip routing
    
    switch1(config)#interface fa0/24
    
    switch1(config-if)#no switchport
    
    switch1(config-if)#ip address 192.168.1.1 255.255.255.252
    
    switch1(config-if)#no shutdown
    
    switch1(config-if)#exit
    
    switch1(config)#ip route 10.1.1.0 255.255.255.0 192.168.1.2
    
    switch1(config)#exit
    
    switch1#show ip route
    
    switch1#write

    [OK]

**2****、**

Router>enable
    
    Router#config t
    
    Router(config)#hostname R-WR-1
    
    R-WR-1(config)#ip routing
    
    R-WR-1(config)#int fa0/0
    
    R-WR-1(config-if)#no shutdown
