华为DHCP中继配置

??????峤

　　1.搭建拓扑图并命名
　　[Huawei]sysname DHCP
　　[DHCP]
　　[Huawei]sysname R1
　　[R1]
　　2.2台路由器上开启dhcp服务并配置ip
　　[DHCP]interface g0/0/0
　　[DHCP-GigabitEthernet0/0/0]ip add
　　[DHCP-GigabitEthernet0/0/0]ip address 192.168.1.2  24
　　Feb  6 2018 15:29:35-08:00 DHCP %%01IFNET/4/LINK_STATE(l)[0]:The line protocol I
　　P on the interface GigabitEthernet0/0/0 has entered the UP state.
　　[DHCP-GigabitEthernet0/0/0]ip address 192.168.1.1 24
　　[DHCP-GigabitEthernet0/0/0]q
　　[DHCP]dhcp
　　[DHCP]dhcp en
　　[DHCP]dhcp enable
　　Info: The operation may take a few seconds. Please wait for a moment.done.
　　[DHCP]
　　[R1]interface GigabitEthernet 0/0/0
　　[R1-GigabitEthernet0/0/0]ip add
　　[R1-GigabitEthernet0/0/0]ip address 192.168.1.2 24
　　Feb  6 2018 15:30:02-08:00 R1 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP
　　on the interface GigabitEthernet0/0/0 has entered the UP state.
　　[R1-GigabitEthernet0/0/0]q
　　[R1]dhcp enable
　　Info: The operation may take a few seconds. Please wait for a moment.done.
　　[R1-GigabitEthernet0/0/1]ip address 192.168.2.254  24
　　Feb  6 2018 15:34:28-08:00 R1 %%01IFNET/4/LINK_STATE(l)[1]:The line protocol IP
　　on the interface GigabitEthernet0/0/1 has entered the UP state.
　　[R1-GigabitEthernet0/0/1]
　　3.配置地址池、路由
　　[DHCP]ip pool p1
　　Info: It's successful to create an IP address pool.
　　配置网段
　　[DHCP-ip-pool-p1]network 192.168.2.254 mask 24
　　配置网关
　　[DHCP-ip-pool-p1]gateway-list 192.168.2.254
　　配置默认路由
　　[DHCP]ip route-static 0.0.0.0  0.0.0.0  192.168.1.2
　　4.配置dhcp中继
　　DHCP的g0/0/0应用基于全局dhcp
　　[DHCP-GigabitEthernet0/0/0]dhcp select global
　　R1上配置中继
　　[R1]interface g0/0/1

　　[R1-GigabitEthernet0/0/1]dhcp  select>
　　[R1-GigabitEthernet0/0/1]dhcp >　　5.测试
　　PC>ipconfig
　　Link local IPv6 address...........: fe80::5689:98ff:fe79:652f
　　IPv6 address......................: :: / 128
　　IPv6 gateway......................: ::
　　IPv4 address......................: 192.168.2.253
　　Subnet mask.......................: 255.255.255.0
　　Gateway...........................: 192.168.2.254
　　Physical address..................: 54-89-98-79-65-2F
　　DNS server........................:
　　6.配置dns、地址排除、租期并测试
　　[DHCP]ip pool p1
　　[DHCP-ip-pool-p1]dn
　　[DHCP-ip-pool-p1]dns-list 8.8.8.8
　　[DHCP-ip-pool-p1]excluded-ip-address 192.168.2.100 192.168.2.252
　　[DHCP-ip-pool-p1]
　　[DHCP-ip-pool-p1]lease day 3
　　PC>ipconfig
　　Link local IPv6 address...........: fe80::5689:98ff:fea6:606e
　　IPv6 address......................: :: / 128
　　IPv6 gateway......................: ::
　　IPv4 address......................: 192.168.2.99
　　Subnet mask.......................: 255.255.255.0
　　Gateway...........................: 192.168.2.254
　　Physical address..................: 54-89-98-A6-60-6E
　　DNS server........................: 8.8.8.8

7.查看dhcp地址池地址使用状况
　　<DHCP>display ip pool name p1 used
　　Pool-name      : p1
　　Pool-No        : 0
　　Lease          : 3 Days 0 Hours 0 Minutes
　　Domain-name    : -
　　DNS-server0    : 8.8.8.8
　　NBNS-server0   : -
　　Netbios-type   : -
　　Position       : Local           Status           : Unlocked
　　Gateway-0      : 192.168.2.254
　　Mask           : 255.255.255.0
　　*** instance   : --
