Cisco三层交换机DHCP中继简单配置
1,简单案例拓扑图。
2,在DHCP服务器上创建两个VLAN (vlan4和vlan5)
3,三层交换机上创建三个VLAN(vlan4、vlan5、vlan100)
3,在三个VLAN中加入相应的端口。
4,配置VLAN4、VLAN5、VLAN100的地址及VLAN4、VLAN5的DHCP中继。(VLAN4省略)
5,配置好之后PING下各VLAN和DHCP服务器。
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

6,从DHCP上PING三层交换。
7,客户端获取的IP地址。
8,查看客户端和交换机ARP记录。
DHCPSVR#show mac-address-table vlan 5
Destination Address Address Type VLAN Destination Port
