Implementation of interworking across VLAN networks using single-arm routing technology
1. Experimental requirements
PC1 belongs to vlan10, PC2 belongs to vlan20,PC3, belongs to vlan30,PC4, belongs to vlan10.
Use dhcp to obtain the IP address automatically.
Single-arm routing technology is used to realize the interworking of the whole network.

Enterconfiguration commands, one per line. End with CNTL/Z.
R1 (config) # intfa0/0

3. The experimental results are verified.
