一
二:
- 实现全网可达。
- 使所有 PC 通过 DHCP 获取 IP 地址
三:
1、划分地址、进行地址配置
2、vlan 配置
划分 vlan;
更改接口的链路类型,将相应的接口加入 vlan;
在 trunk 链路上放行网络中的 vlan
3、配置子接口;
4、DHCP 配置
四:
1:
- VLAN 划分:
- 左边(SW1、SW2):
- VLAN 2:192.168.1.0/24
- VLAN 3:192.168.2.0/24
- 右边(SW3):
- VLAN 2:192.168.3.0/24
- VLAN 3:192.168.4.0/24
- 左边(SW1、SW2):
2.vlan配置
slw1:
# 创建VLAN 2和VLAN 3 vlan 2 vlan 3 # 将接口加入VLAN interface Ethernet 0/0/2 port link-type access port default vlan 2 interface Ethernet 0/0/3 port link-type access port default vlan 3 # 配置Trunk接口(连接SW2) interface Ethernet 0/0/1 port link-type trunk port trunk allow-pass vlan 2 3
slw2:
# 创建VLAN 2和VLAN 3 vlan 2 vlan 3 # 将接口加入VLAN interface Ethernet 0/0/3 port link-type access port default vlan 2 interface Ethernet 0/0/4 port link-type access port default vlan 3 # 配置Trunk接口(连接SW1) interface Ethernet 0/0/2 port link-type trunk port trunk allow-pass vlan 2 3 # 配置Trunk接口(连接R1) interface Ethernet 0/0/1 port link-type trunk port trunk allow-pass vlan 2 3
slw3:
# 创建VLAN 2和VLAN 3 vlan 2 vlan 3 # 将接口加入VLAN interface Ethernet 0/0/2 port link-type access port default vlan 2 interface Ethernet 0/0/3 port link-type access port default vlan 3 # 配置Trunk接口(连接R1) interface Ethernet 0/0/1 port link-type trunk port trunk allow-pass vlan 2 3
3.R2接口配置虚拟接口
interface GigabitEthernet0/0/0.2
dot1q termination vid 2
ip address 192.168.1.254 255.255.255.0
arp broadcast enable
#interface GigabitEthernet0/0/0.3
dot1q termination vid 3
ip address 192.168.2.254 255.255.255.0
arp broadcast enable
#interface GigabitEthernet0/0/1.2
dot1q termination vid 2
ip address 192.168.3.254 255.255.255.0
arp broadcast enable
#interface GigabitEthernet0/0/1.3
dot1q termination vid 3
ip address 192.168.4.254 255.255.255.0
arp broadcast enable
#
4.dhcp配置
dhcp enable
#
ip pool A
gateway-list 192.168.1.254
network 192.168.1.0 mask 255.255.255.0
dns-list 8.8.8.8 114.114.114.114
#
ip pool B
gateway-list 192.168.2.254
network 192.168.2.0 mask 255.255.255.0
dns-list 8.8.8.8 114.114.114.114
#
ip pool C
gateway-list 192.168.3.254
network 192.168.3.0 mask 255.255.255.0
dns-list 8.8.8.8 114.114.114.114
#
ip pool D
gateway-list 192.168.4.254
network 192.168.4.0 mask 255.255.255.0
dns-list 8.8.8.8 114.114.114.114
#
5.在r1的虚拟接口上启动dhcp
dhcp select global
五:验证
1.slw的配置vlan
dhcp:
ping 测试
