?1,簡單案例拓撲圖。

2,在DHCP服務器上創建兩個VLAN (vlan4和vlan5)

3,三層交換機上創建三個VLAN(vlan4、vlan5、vlan100)

3,在三個VLAN中加入相應的端口。

4,配置VLAN4、VLAN5、VLAN100的地址及VLAN4、VLAN5的DHCP中繼。(VLAN4省略)

5,配置好之后PING下各VLAN和DHCP服務器。

DHCPSVR#ping 10.1.3.1

?

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.1.3.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

DHCPSVR#ping 10.1.4.1

?

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.1.4.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

DHCPSVR#ping 10.1.5.1

?

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.1.5.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/3/4 ms

?

DHCPSVR#ping 10.1.3.201

?

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.1.3.201, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/26/60 ms

DHCPSVR#

6,從DHCP上PING三層交換。

7,客戶端獲取的IP地址。

8,查看客戶端和交換機ARP記錄。

DHCPSVR#show mac-address-table vlan 5

Destination Address? Address Type? VLAN? Destination Port

-------------------? ------------? ----? --------------------

cc02.04dc.0000????????? Self????????? 5???? Vlan5

000c.29f4.ee4e????????? Dynamic?????? 5???? FastEthernet0/7

?

DHCPSVR#

,至此結束。
