项目实战 - 基础交换网络设计

  • 需求
    • 公司有三个部门，财务部，市场部，技术部，为了内网安全，给每个部门单独划分一个VLAN
    • 财务部：vlan10、市场部：vlan20、技术部：vlan30
    • 公司所有部门，所有VLAN内的主机都通过DHCP服务器分发IP地址
    • 每个部门，每个VLAN的网关地址都为，192.168.xx.254
    • SW5中每个vlanif 虚接口地址都为 192.168.xx.254
    • SW5通过vlanif50与DHCP进行通信，DHCP服务器管理IP：192.168.50.1
    • 所有的PC都通过SW5与DHCP服务器进行通信，获取IP地址，所以SW5是DHCP中继

一、IP、VLAN、Routing

  • PC

  • SW1

    [SW1]vlan batch 10 20 30
[SW1]port-group group-member g0/0/1 g0/0/3 g0/0/4
[SW1-port-group]port link-type access
[SW1-port-group]port default vlan 10
[SW1-port-group]quit
[SW1]int g0/0/2
[SW1-GigabitEthernet0/0/2]port link-type trunk
[SW1-GigabitEthernet0/0/2]port trunk allow-pass vlan all

  • SW2

    [SW2]vlan batch 10 20 30
[SW2]int g0/0/1
[SW2-GigabitEthernet0/0/1]port link-type access
[SW2-GigabitEthernet0/0/1]port default vlan 20
[SW2-GigabitEthernet0/0/1]int g0/0/2
[SW2-GigabitEthernet0/0/2]port link-type trunk
[SW2-GigabitEthernet0/0/2]port trunk allow-pass vlan all

  • SW3

    [SW3]vlan batch 10 20 30
[SW3]int g0/0/1
[SW3-GigabitEthernet0/0/1]port link-type access
[SW3-GigabitEthernet0/0/1]port default vlan 30
[SW3-GigabitEthernet0/0/1]int g0/0/2
[SW3-GigabitEthernet0/0/2]port link-type trunk
[SW3-GigabitEthernet0/0/2]port trunk allow-pass vlan all

  • HX - SW5

    [HX-SW5]vlan batch 10 20 30 50
[HX-SW5]port-group group-member g0/0/1 to g0/0/3
[HX-SW5-port-group]port link-type trunk
[HX-SW5-port-group]port trunk allow-pass vlan all
[HX-SW5-port-group]quit
[HX-SW5]int g0/0/5
[HX-SW5-GigabitEthernet0/0/5]port link-type access
[HX-SW5-GigabitEthernet0/0/5]port default vlan 50
[HX-SW5-GigabitEthernet0/0/5]quit
[HX-SW5]int Vlanif 50
[HX-SW5-Vlanif50]ip add 192.168.50.251 24

  • AR3 - DHCP

    [AR3-DHCP]int g0/0/1
[AR3-DHCP-GigabitEthernet0/0/1]ip add 192.168.50.1 24
[AR3-DHCP-GigabitEthernet0/0/1]quit
[AR3-DHCP]ip route-static 0.0.0.0 0 192.168.50.251

二、DHCP

1、配置

  • AR3 - DHCP

    [AR3-DHCP]dhcp enable 
[AR3-DHCP]ip pool vlan10
[AR3-DHCP-ip-pool-vlan10]network 192.168.10.0 mask 24
[AR3-DHCP-ip-pool-vlan10]gateway-list 192.168.10.254
[AR3-DHCP-ip-pool-vlan10]dns-list 8.8.8.8
[AR3-DHCP-ip-pool-vlan10]quit
[AR3-DHCP]ip pool vlan20
[AR3-DHCP-ip-pool-vlan20]network 192.168.20.0 mask 24
[AR3-DHCP-ip-pool-vlan20]gateway-list 192.168.20.254
[AR3-DHCP-ip-pool-vlan20]dns-list 8.8.8.8
[AR3-DHCP-ip-pool-vlan20]quit
[AR3-DHCP]ip pool vlan30
[AR3-DHCP-ip-pool-vlan30]network 192.168.30.0 mask 24
[AR3-DHCP-ip-pool-vlan30]gateway-list 192.168.30.254
[AR3-DHCP-ip-pool-vlan30]dns-list 8.8.8.8
[AR3-DHCP-ip-pool-vlan30]quit
[AR3-DHCP]int g0/0/1
[AR3-DHCP-GigabitEthernet0/0/1]dhcp select global

  • HX - SW5

    [HX-SW5]dhcp enable 
[HX-SW5]int Vlanif 10
[HX-SW5-Vlanif10]ip add 192.168.10.254 24
[HX-SW5-Vlanif10]dhcp select relay
[HX-SW5-Vlanif10]dhcp relay server-ip 192.168.50.1
[HX-SW5-Vlanif10]int Vlanif 20
[HX-SW5-Vlanif20]ip add 192.168.20.254 24
