DHCP Lab 2

In a Switching DHCP Lab 2 scenario, the focus likely extends to more advanced configurations and testing of DHCP (Dynamic Host Configuration Protocol) services within a switching environment. This lab may involve complex network topologies with multiple interconnected switches and routers, requiring participants to implement and troubleshoot DHCP services across various VLANs. The lab might explore features such as DHCP options, reservation configurations, and relay agent setups on the switches to ensure efficient IP address assignment and network management. Participants may also delve into DHCP security measures, such as DHCP snooping, to protect against unauthorized DHCP servers and mitigate potential security threats. By engaging in Switching DHCP Lab 2, participants gain a deeper understanding of DHCP intricacies in switched networks, preparing them for real-world scenarios where robust DHCP configurations are crucial for maintaining a scalable and secure network infrastructure.

Task 2: Configure IPv4 DHCP

Step 1: In the configuration mode of router configure IPv4 DHCP by following command:

Router1:
interface fastethernet 0/0 
no shutdown 
interface fastethernet 0/0.1 
encapsulation dotlq 100 
ip address 100.0.0.1 255.255.255.0
interface fastethernet 0/0.2 
encapsulation dot1q 200 
ip address 200.0.0.1 255.255.255.0 
exit

ip dhcp pool VLAN100 
network 100.0.0.0 255.255.255.0 
default-router 100.0.0.1 
exit 
ip dhcp excluded-address 100.0.0.1 
ip dhcp pool VLAN200 
network 200.0.0.0 255.255.255.0 
default-router 200.0.0.1 
exit 
ip dhcp excluded-address 200.0.0.1

Switch1:
interface fastethernet 0/1 
switchport mode trunk 
exit 
interface fastethernet 0/2 
switchport access vlan 100 
switchport mode access 
interface fastethernet 0/3 
switchport access vlan 200 
switchport mode access 
exit

Configure the HOST to obtain IP from DHCP.
