Cisco DHCP and VLAN comprehensive experiment

Lab content:

The IP addresses of PC1 and PC2 must be obtained through the DHCP Server. R1 performs single-arm routing and DHCP Relay. The IP address of f2/0 on the R2 interface is 192.168.3.1. PC1 belongs to vlan10, PC2 belongs to vlan20, and R3 (DHCP Server) belongs to VLAN30.

PC1 belongs to the 192.168.1.0 network segment, the gateway is 192.168.1.254 PC2 belongs to the 192.168.2.0 network segment, and the gateway is 192.168.2.254

Tutorial ideas:

Configure vlan 10, 20, 30 on S1 and e0/2 as the trunk Port

On R1. Each sub-interface must specify the encapsulation mode and IP address of the DHCP Server.

Configure the default route to the host on the DHCP Server

Lab Verification:

No IP address for start PC1

PC1 uses the DCHP request IP Address

PC1 successfully requests an IP address.
