问题：sw1可以ping通sw4不，如何做？答：可以，在sw1上配置一个明细路由往sw2方向即可。

（1）配置

sw1:

interface GE1/0/0

 undo portswitch

 undo shutdown

 ip address 192.168.1.1 255.255.255.0

#

ip route-static 192.168.1.100 255.255.255.255 192.168.1.254

sw2:

interface GE1/0/0

 undo portswitch

 undo shutdown

 ip address 192.168.2.254 255.255.255.0

#

interface GE1/0/1

 undo portswitch

 undo shutdown

 ip address 192.168.1.254 255.255.255.0

ip route-static 192.168.1.100 255.255.255.255 192.168.2.1

sw3:

interface GE1/0/1

 undo portswitch

 undo shutdown

 ip address 192.168.1.254 255.255.255.0

#

interface GE1/0/2

 undo portswitch

 undo shutdown

 ip address 192.168.2.1 255.255.255.0

ip route-static 0.0.0.0 0.0.0.0 192.168.2.254

sw4:

interface GE1/0/0

 undo portswitch

 undo shutdown

 ip address 192.168.1.100 255.255.255.0

ip route-static 0.0.0.0 0.0.0.0 192.168.1.254

测试：sw1ping不通，但是sw2可以ping通sw4

结论：

1、如果静态路由的目的地址与下一跳地址在同一网段，则不生效。

2、静态路由也可以优于直连路由。
