VLAN configuration and application (take Huawei ENSP as an example)

If there is a mistake , Please kindly understanding ！

This article is only for my study notes , For reference only , If offended , Please contact the author for deletion ！！！

Introduction to basic knowledge ：

    establish vlan：

[Huawei]vlan 2

      draw ⼊ Pick up ⼝：

[Huawei]interface e0/0/1
[Huawei-Ethernet0/0/1]port link-type access  Change mode to connect ⼊
[Huawei-Ethernet0/0/1]port default vlan 2  draw ⼊vlan 2

    trunk The encapsulation mode of ：

Category	dot1q	isl
size	4b	20b
Support agreement	only ⽀ a tcp/ip	⽀ Hold all agreements
	The public agreement	cisco private

    fictitious ⼦ Pick up ⼝：

[dhcp]interface g0/0/0.1
[dhcp-GigabitEthernet0/0/0.1]dot1q termination vid 2
[dhcp-GigabitEthernet0/0/0.1]ip address 192.168.1.1 24

    transfer ⽤：

[dhcp]interface g0/0/0.1
[dhcp-GigabitEthernet0/0/0.1]dhcp select global
[dhcp-GigabitEthernet0/0/0.1]arp broadcast enable

Experimental Topology ：

  One 、 by PC1、PC2、PC3、PC4 Delegate designation IP

      Set for switch vlan: 

[Huawei]vlan 2
[Huawei]vlan 3
[Huawei]vlan 4
[Huawei]vlan 5

[Huawei]interface e0/0/2
[Huawei-Ethernet0/0/2]port link-type access 	
[Huawei-Ethernet0/0/2]port default vlan 2
[Huawei]interface e0/0/3
[Huawei-Ethernet0/0/3]port link-type access
[Huawei-Ethernet0/0/3]port default vlan 3
[Huawei]interface e0/0/4
[Huawei-Ethernet0/0/4]port link-type access
[Huawei-Ethernet0/0/4]port default vlan 4
[Huawei-Ethernet0/0/4]quit
[Huawei]interface e0/0/5
[Huawei-Ethernet0/0/5]port link-type access
[Huawei-Ethernet0/0/5]port default vlan 5
[Huawei-Ethernet0/0/5]quit

    For the switch e0/0/1 Interface setup trunk

[Huawei]interface e0/0/1	
[Huawei-Ethernet0/0/1]port link-type trunk 
[Huawei-Ethernet0/0/1]port trunk allow-pass vlan all

      Configure virtual sub interface IP And divide vlan：

[r1]interface g0/0/0.1	
[r1-GigabitEthernet0/0/0.1]ip address 172.16.1.1 24
[r1]interface g0/0/0.2
[r1-GigabitEthernet0/0/0.2]ip address 172.16.2.1 24
[r1]interface g0/0/0.3
[r1-GigabitEthernet0/0/0.3]ip address 172.16.3.1 24
[r1]interface g0/0/0.4
[r1-GigabitEthernet0/0/0.4]ip address 172.16.4.1 24

[r1]dhcp enable 
[r1]interface g0/0/0.1	
[r1-GigabitEthernet0/0/0.1]dot1q termination vid 2
[r1]interface g0/0/0.2
[r1-GigabitEthernet0/0/0.2]dot1q termination vid 3
[r1]interface g0/0/0.3
[r1-GigabitEthernet0/0/0.3]dot1q termination vid 4
[r1]interface g0/0/0.4
[r1-GigabitEthernet0/0/0.4]dot1q termination vid 5

      Turn on DHCP Service and configuration dhcp

[r1]dhcp enable 

[r1]ip pool 1
[r1-ip-pool-1]network 172.16.1.0 mask 255.255.255.0
[r1-ip-pool-1]gateway-list 172.16.1.1	
[r1-ip-pool-1]dns-list 8.8.8.8
[r1-ip-pool-1]quit

[r1]ip pool 2
[r1-ip-pool-2]network 172.16.2.0 mask 255.255.255.0
[r1-ip-pool-2]gateway-list 172.16.2.1
[r1-ip-pool-2]dns-list 8.8.8.8
[r1-ip-pool-2]quit

[r1]ip pool 3
[r1-ip-pool-3]network 172.16.3.0 mask 255.255.255.0
[r1-ip-pool-3]dns-list 8.8.8.8
[r1-ip-pool-3]gateway-list 172.16.3.1
[r1-ip-pool-3]quit

[r1]ip pool 4
[r1-ip-pool-4]network 172.16.4.0 mask 255.255.255.0
[r1-ip-pool-4]gateway-list 172.16.4.1
[r1-ip-pool-4]dns-list 8.8.8.8
[r1-ip-pool-4]quit

    call ：

[r1]interface g0/0/0.1
[r1-GigabitEthernet0/0/0.1]dhcp select global 		
[r1-GigabitEthernet0/0/0.1]arp broadcast  enable 
[r1-GigabitEthernet0/0/0.1]quit
[r1]interface g0/0/0.2
[r1-GigabitEthernet0/0/0.2]dhcp select global
[r1-GigabitEthernet0/0/0.2]arp broadcast enable
[r1-GigabitEthernet0/0/0.2]quit
[r1]interface g0/0/0.3
[r1-GigabitEthernet0/0/0.3]dhcp select global
[r1-GigabitEthernet0/0/0.3]arp broadcast enable
[r1-GigabitEthernet0/0/0.3]quit
[r1]interface g0/0/0.4
[r1-GigabitEthernet0/0/0.4]dhcp select global
[r1-GigabitEthernet0/0/0.4]arp broadcast enable
[r1-GigabitEthernet0/0/0.4]quit

    Similarly, the above operation is PC5、PC6 Delegate designation IP.

Two 、 Configure the router nodes IP Address

    With routers r2 For example ：

[r2]interface LoopBack 0
[r2-LoopBack0]ip address 2.2.2.2 32
[r2]interface g0/0/0	
[r2-GigabitEthernet0/0/0]ip address 12.1.1.2 24
[r2]interface g0/0/1
[r2-GigabitEthernet0/0/1]ip address 23.1.1.1 24

3、 ... and 、 utilize OSPF agreement , Divide three routers into one area

  With routers r2 For example ：

[r2]ospf 100 router-id 2.2.2.2
[r2-ospf-100]area 1	
[r2-ospf-100-area-0.0.0.1]network  0.0.0.0 255.255.255.255

Four 、 test

  The above process is what we want , Welcome friends to correct ！ Thank you very much !
