HCIP VLAN实验

拓扑图

配置和分析

分析

从题目来看，因为 pc 1 3都是vlan2而且还是不同网段，pc 2 4 5 6在同一网段，所以可以将pc  2 5 4 6分在一个网段， pc 1 3在同一个网段
pc4不通5 6 ，那就在5 6 的混杂接口上不允许4通过

配置

LSW1

pc1和pc3的接口正常配access就行了，LSW1与LSW2直接可以直接设置trunk干道允许所有

---

[LSW1-Ethernet0/0/1]port hybrid untagged vlan 3 to 6    
[LSW1-Ethernet0/0/1]port hybrid tagged vlan 2

---

[LSW1-Ethernet0/0/4]port hybrid pvid vlan 3
[LSW1-Ethernet0/0/4]port hybrid untagged vlan 2 to 6

---

[LSW1-Ethernet0/0/6]port hybrid pvid vlan 4
[LSW1-Ethernet0/0/6]port hybrid untagged vlan 2 to  6

---

LSW2

[LSW2-Ethernet0/0/2]port hybrid pvid vlan 5
[LSW2-Ethernet0/0/2]port hybrid untagged vlan 2 3 5   只允许 2 3 5 通过

---

---

[LSW2-Ethernet0/0/3]port hybrid pvid vlan 6
[LSW2-Ethernet0/0/3]port hybrid untagged vlan 2 3 6   只允许 2 3 6 通过

---

[LSW2]int e0/0/1
[LSW2-Ethernet0/0/1]port link-type trunk 
[LSW2-Ethernet0/0/1]port trunk allow-pass vlan 2 to 6  干道可以直接允许所有

---

[LSW1]int e0/0/2
[LSW1-Ethernet0/0/2]port link-type trunk 
[LSW1-Ethernet0/0/2]port trunk allow-pass vlan 2 to 6

R1

[R1]ip pool 1
Info: It's successful to create an IP address pool.
[R1-ip-pool-1]network 192.168.1.0 mask 24
[R1-ip-pool-1]gateway-list 192.168.1.1

---

[R1-ip-pool-1]ip pool 2 
Info: It's successful to create an IP address pool.
[R1-ip-pool-2]network 192.168.2.0 mask 24
[R1-ip-pool-2]gateway-list 192.168.2.1

---

[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip address 192.168.1.1 24
[R1-GigabitEthernet0/0/0]dhcp  select global 

---

[R1]int g0/0/0.1
[R1-GigabitEthernet0/0/0.1]dot1q termination vid 2  这个给pc3的vlan 2 
[R1-GigabitEthernet0/0/0.1]ip address 192.168.2.1 24
[R1-GigabitEthernet0/0/0.1]arp broadcast enable  注意这个命令不要忘了，子接口是不能发广播的所以要手动开启arp广播
[R1-GigabitEthernet0/0/0.1]dhcp select global 

测试

dhcp获取ip

ICMP测试

pc 4 不通pc 5 6
