The experiment of single-arm routing to realize inter-VLAN communication

Experimental requirements

VLAN 10 Network Segment 192.168.10.0

PC0 192.168.10.2

VLAN 20 Network Segment 192.168.20.0

PC1 192.168.20.2

Experiment 1 using routers to achieve one-arm routing

Topology

s switch Configuration

Switch (config) #vlan 10

Router (config-subif) #ip address 192.168.20.1 255.255.255.0

Router (config-subif) #no shutdown

Test

Set the PC0 IP to 192.168.10.2

Gateway: 192.168.10.1

PC1 IP is set to 192.168.20.2

Gateway: 192.168.20.1

Use PC1 ping pc0
