1.路由器設(shè)置IP

[Huawei]int g0/0/0

[R1-GigabitEthernet0/0/0]ip address 192.168.1.254 24

[R1-GigabitEthernet0/0/0]int g0/0/1

[R1-GigabitEthernet0/0/1]ip address 192.168.2.1 24

[R3]int g0/0/1

[R3-GigabitEthernet0/0/1]ip address 192.168.2.2 24

[R3-GigabitEthernet0/0/1]int g0/0/0

[R3-GigabitEthernet0/0/0]ip address 192.168.3.1 24

[R4]int g0/0/1

[R4-GigabitEthernet0/0/1]ip address 192.168.4.1 24

[R4-GigabitEthernet0/0/1]int g0/0/0

[R4-GigabitEthernet0/0/0]ip address 192.168.3.2.24

2.配置靜態(tài)路由(默認(rèn)路由)

[R1]ip route-static 0.0.0.0 0.0.0.0 192.168.2.2

[R4]ip route-static 0.0.0.0 0.0.0.0 192.168.3.1

3配置DHCP服務(wù)器

3.1創(chuàng)建兩個(gè)IP地址池

[R1]dhcp enable

[R1]ip pool ppp

[R1i-ip-pool-ppp]network 192.168.1.0 mask 24

[R1-ip-pool-ppp]gateway-list 192.168.1.254

[R1-ip-pool-ppp]dns

[R1-ip-pool-ppp]dns-list 8.8.8.8.

[R1-ip-pool-ppp]lease day 1

[R1-ip-pool-ppp]excluded-ip-address 192.168.1.10 192.168.1.20

[R1-ip-pool-ppp]q

[R1]ip pool ooo

[R1i-ip-pool-ooo]network 192.168.4.0 mask 24

[R1-ip-pool-ooo]gateway-list 192.168.2.1

[R1-ip-pool-ooo]dns

[R1-ip-pool-ooo]dns-list 8.8.8.8

[R1i-ip-pool-ooo]lease day 1

3.2端口啟動(dòng)dhcp 為全局連接

[R1]int g0/0/1

[R1-GigabitEthernet0/0/1]dhcp select global

R1]int g0/0/0

[R1-GigabitEthernet0/0/0]dhcp select global

配置中繼代理

[relay]dhcp enable

[relay]int g0/0/1

[relay-GigabitEthernet0/0/1]dhcp select relay

[relay-GigabitEthernet0/0/1]dhcp relay server-ip 192.168.2.1
