华为 单臂路由+DHCP 实验 (2021-03-24)

​

在全局模式下配置DHCP

SW1的配置：
vlan batch 10 20
#
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 10 20
#
interface GigabitEthernet0/0/2
 port link-type access
 port default vlan 10
#
interface GigabitEthernet0/0/3
 port link-type access
 port default vlan 20

AR1的配置：
dhcp enable
#
ip pool DHCP-vlan10
 gateway-list 192.168.10.254 
 network 192.168.10.0 mask 255.255.255.0 
 lease day 3 hour 0 minute 0 
 dns-list 192.168.10.254 8.8.8.8 
 domain-name www.google.com
#
ip pool DHCP-vlan20
 gateway-list 192.168.20.254 
 network 192.168.20.0 mask 255.255.255.0 
 lease day 3 hour 0 minute 0 
 dns-list 192.168.20.254 8.8.8.8 
 domain-name www.google.com
#

[AR1]interface GigabitEthernet 0/0/0.?
  <1-4096>  GigabitEthernet interface subinterface number       //华为路由器的路由子接口最多能支持4096个
#
interface GigabitEthernet0/0/0.1
 dot1q termination vid 10
 ip address 192.168.10.254 255.255.255.0 
 arp broadcast enable
 dhcp select global
#
interface GigabitEthernet0/0/0.2
 dot1q termination vid 20
 ip address 192.168.20.254 255.255.255.0 
 arp broadcast enable
 dhcp select global

注：
dhcp select global 是选择全局的地址池给DHCP客户端使用
dhcp select interface 是选择接口的地址池给DHCP客户端使用

---

在接口下配置DHCP，比如在物理接口，vlanif接口，环回口下等等

​

SW2的配置：

vlan batch 10 20

#

interface Ethernet0/0/1

port link-type trunk

port trunk allow-pass vlan 10 20

#

interface Ethernet0/0/2

port link-type access

port default vlan 10

#

interface Ethernet0/0/3

port link-type access

port default vlan 20

 

 

SW1的配置：

interface GigabitEthernet0/0/1

port link-type trunk

port trunk allow-pass vlan 10 20

#

vlan batch 10 20

#

dhcp enable

#

interface Vlanif10

ip address 192.168.10.254 255.255.255.0

dhcp select interface

dhcp server lease day 3 hour 0 minute 0

dhcp server dns-list 192.168.10.254 8.8.8.8

dhcp server next-server 192.168.10.254

dhcp server domain-name www.google.com

[Huawei-Vlanif10]dhcp server excluded-ip-address 192.168.10.1 192.168.10.5    //如果要从地址池中排除/保留某些ip地址，用这条命令

#

interface Vlanif20

ip address 192.168.20.254 255.255.255.0

dhcp select interface

dhcp server lease day 3 hour 0 minute 0

dhcp server dns-list 192.168.20.254 8.8.8.8

dhcp server next-server 192.168.20.254
