实验拓扑
配置步骤 (在路由器上配置)
- (1) # 配置接口的 IP 地址.
- <H3C> system-view
- [H3C] interface g 0/0
- [[H3C-GigabitEthernet0/0]] ip address 192.168.1.254 24
- [[H3C-GigabitEthernet0/0]] quit
- (2)# 启用 DHCP 服务.
- [H3C] dhcp enable
- (4)# 配置 DHCP 地址池 0, 采用动态绑定方式分配 IP 地址.
可分配的网段为 192.168.1.0/24, 租约有效期限为 10 天, DNS 服务器地址为 192.168.1.10.
- [H3C] dhcp server ip-pool 0
- [H3C-dhcp-pool-0] network 192.168.1.0 mask 255.255.255.0
- [H3C-dhcp-pool-0] expired day 10
- [H3C-dhcp-pool-0] dns-list 192.168.1.10
- [H3C-dhcp-pool-0] gateway-list 192.168.1.254
- [H3C-dhcp-pool-0] quit
实验 2:
实验拓扑
这个任务主要是做 DHCP 中继.
DHCP 服务器在路由器上, 而 SWA 上有 3 个 VLAN, 分属于 3 个不同网段,
DHCP 的请求报文是广播, 因此必须在 SWA 上设置中继才能够传到路由器.
配置步骤
- (1) # 配置路由器.
- <H3C> system-view
- [H3C] interface g 0/0
- [[H3C-GigabitEthernet0/0]] ip address 10.1.1.2 30
- [[H3C-GigabitEthernet0/0]] quit
启用 DHCP 服务.
[H3C] dhcp enable
配置 DHCP 地址池 1, 为来自 192.168.1.0/24 网段内的客户端分配地址.
- [H3C] dhcp server ip-pool 1
- [H3C-dhcp-pool-0] network 192.168.10.0 mask 255.255.255.0
- [H3C-dhcp-pool-0] dns-list 8.8.8.8
- [H3C-dhcp-pool-0] gateway-list 192.168.10.254
- [H3C-dhcp-pool-0] quit
配置 DHCP 地址池 2, 为来自 192.168.20.0/24 网段内的客户端分配地址.
- [H3C] dhcp server ip-pool 2
- [H3C-dhcp-pool-0] network 192.168.20.0 mask 255.255.255.0
- [H3C-dhcp-pool-0] dns-list 8.8.8.8
- [H3C-dhcp-pool-0] gateway-list 192.168.20.254
- [H3C-dhcp-pool-0] quit
配置 DHCP 地址池 3, 为来自 192.168.30.0/24 网段内的客户端分配地址.
- [H3C] dhcp server ip-pool 3
- [H3C-dhcp-pool-0] network 192.168.30.0 mask 255.255.255.0
- [H3C-dhcp-pool-0] dns-list 8.8.8.8
- [H3C-dhcp-pool-0] gateway-list 192.168.30.254
- [H3C-dhcp-pool-0] quit
配置静态路由到 192.168.0.0/16 网段
- [H3C]ip route-static 192.168.0.0 16 10.1.1.1
- (2)# 配置 SWA 交换机.
建立 vlan, 并且配置各接口的 IP 地址.
- <H3C>
- system-view [H3C]vlan 10 [H3C-vlan10]quit [H3C]vlan 20 [H3C-vlan20]quit
- [H3C]vlan 30 [H3C-vlan30]quit [H3C]inter range g 1/0/1 to g 1/0/5 [H3C-if-range]port
- link-type access [H3C-if-range]port access vlan 10 [H3C-if-range]quit [H3C]inter
- range g 1/0/6 to g 1/0/10 [H3C-if-range]port link-type access [H3C-if-range]port
- access vlan 20 [H3C-if-range]quit [H3C]inter range g 1/0/11 to g 1/0/15
- [H3C-if-range]port link-type access [H3C-if-range]port access vlan 30 [H3C-if-range]quit
- [H3C]inter vlan 10 [H3C-Vlan-interface10]ip add 192.168.10.254 24 [H3C-Vlan-interface10]quit
- [H3C]inter vlan 20 [H3C-Vlan-interface20]ip add 192.168.20.254 24 [H3C-Vlan-interface20]quit
- [H3C]inter vlan 30 [H3C-Vlan-interface30]ip add 192.168.30.254 24 [H3C-Vlan-interface30]quit
- [H3C] [H3C]inter g 1/0/23 [H3C-GigabitEthernet1/0/23]port link-m r [H3C-GigabitEthernet1/0/23]ip
