出口路由器AR1内网部分配置
sysname AR1
interface GigabitEthernet0/0/0
ip address 10.1.10.2 255.255.255.0
interface GigabitEthernet0/0/1
ip address 10.1.20.2 255.255.255.0
ospf 1
area 0.0.0.0
network 10.1.10.2 0.0.0.0
network 10.1.20.2 0.0.0.0
//常规配置，部署与核心交换机间的OSPF协议
配置完成后查看OSPF邻居正常
DHCP服务部署
说明：为了展示DHCP SERVER的两种常见部署方式。有线PC的DHCP采用三层旁挂，无线设备的DHCP采用部署在核心。
DHCP旁挂部署
接入交换机SW6配置，相关配置说明间接入交换机SW3的说明
sysname SW6
vlan batch 10 20 40
stp edged-port default
stp region-configuration
region-name HUAWEI
revision-level 12
instance 10 vlan 10 40
instance 20 vlan 20
active region-configuration
Quit
interface GigabitEthernet0/0/1

DHCP SERVER AR3 配置
sysname AR3
dhcp enable
//开始DHCP服务
ip pool 10
gateway-list 192.168.10.254
network 192.168.10.0 mask 255.255.255.0
excluded-ip-address 192.168.10.200 192.168.10.253
ip pool 20
gateway-list 192.168.20.254
network 192.168.20.0 mask 255.255.255.0
excluded-ip-address 192.168.20.200 192.168.20.253
//配置VLAN10 20地址池，排除相关已使用地址
interface GigabitEthernet0/0/0
ip address 172.16.1.1 255.255.255.0
dhcp select global
//配置DHCP服务接口
ip route-static 0.0.0.0 0.0.0.0 172.16.1.254
//配置默认路由
核心交换机SW1 SW2 配置DHCP中继
dhcp enable
//开启DHCP服务
interface Vlanif10
dhcp select relay
dhcp relay server-ip 172.16.1.1
interface Vlanif20
dhcp select relay
dhcp relay server-ip 172.16.1.1
//VLAN IF接口下配置DHCP中继服务
配置完成后VLAN10 20PC获取地址正常，PING出口路由器正常
