1.1 Network 1: Xinhua Three single-arm routing network experiment
1.1.1 Experimental topology
Remember to like and follow after reading! ! ! Thank you!
1.1.2. Experimental tasks and objectives
(1) Realize the VLAN isolation of the second-tier broadcast domain of the above-mentioned networking and the full connectivity of the third-tier network.
(2) Analyze the broadcast domain size of Vlan10 and Vlan20 and the communication range of the Layer 2 network.
(3) Analyze the three-layer communication process and the two-layer communication process of PC1 to PC4.
(4) Master the application of hierarchical configuration and troubleshooting in LAN projects.
(5) Master the three-layer logical topology and the two-layer logical topology abstraction.
(6) Master the judgment of the broadcast domain size and the analysis of the communication range of the second-layer network.
(7) Master the hierarchical data flow analysis under the VLAN environment.

1.1.4. VLAN configuration
SW1 configuration
[SW1]vlan 10 // Create vlan 10
[SW1-vlan10]port GigabitEthernet 1/0/2 // Add interface to vlan 10
[SW1]interface GigabitEthernet 1/0/2 // Enter interface 1/0/2
[SW1-GigabitEthernet1/0/2]port link-type access // Configure to access mode
[SW1]interface GigabitEthernet 1/0/3 // create vlan 20
[SW1]interface GigabitEthernet 1/0/3 // enter interface
1/0/3 [SW1-GigabitEthernet1/0/2]port link-type access // Configure to access mode
SW2 configuration
[SW2]vlan 10 // Create vlan 10
[SW2-vlan10]port GigabitEthernet 1/0/2 // Add interface to vlan 10
[SW2]interface GigabitEthernet 1/0/2 // Enter interface 1/0/2
[SW2-GigabitEthernet1/0/2]port link-type access // Configure to access mode
[SW2]vlan 20 // Create vlan 20
[SW2]interface GigabitEthernet 1/0/3 // Enter interface 1/0/3
[ SW2-GigabitEthernet1/0/3]port link-type access // Configure to access mode
1.1.5. Trunk configuration
(1) SW1-SW2 Trunk link commissioning
SW1 configuration
[SW1]interface GigabitEthernet 1/0/1
[SW1-GigabitEthernet1/0/1]port link-type trunk The interface is configured as a trunk port
[SW1-GigabitEthernet1/0/1]port trunk permit vlan all allows all VLANs to pass
SW2 configuration
[SW2]interface GigabitEthernet 1/0/1
[SW2-GigabitEthernet1/0/1]port link-type trunk The interface is configured as a trunk port
[SW2-GigabitEthernet1/0/1]port trunk permit vlan all allows all VLANs to pass
