DHCP

Configuring a Basic DHCPv4 Server

Step 1. Excluding IPv4 Addresses

R1(config)# ip dhcp excluded-address 192.168.10.1 192.168.10.9

R1(config)# ip dhcp excluded-address 192.168.10.254

Step 2. Configuring a DHCPv4 Pool

R1(config)#ip dhcp pool LAN-POOL-1

R1(dhcp-config)#

Step 3. Configuring Specific Tasks

DHCPv4 Example

R1(config)# ip dhcp excluded-address 192.168.10.1 192.168.10.9

R1(config)# ip dhcp excluded-address 192.168.10.254

R1(config)#ip dhcp pool LAN-POOL-1

R1(dhcp-config)#network 192.168.10.0 255.255.255.0

R1(dhcp-config)#default-router 192.168.10.1

R1(dhcp-config)#dns-server 192.168.11.5

domain-name example.com

R1(dhcp-config)#exit

Verifying DHCPv4

R1#show running-config | section dhcp

R1#show ip dhcp server statistics

DHCPv4 Relay

R1(config)#interface g0/0

R1(config-if)ip helper--address 192.168.11.6
