In the below example we configure R1’s Fa0/0 to use DHCP.

R1(config-if)#ip address dhcp
R1(config-if)#
*Mar 1 01:39:29.295: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 10.1.1.2 (FastEthernet0/0) is down: interface down
R1(config-if)#
*Mar 1 01:39:40.455: %DHCP-6-ADDRESS_ASSIGN: Interface FastEthernet0/0 assigned DHCP address 10.1.1.1, mask 255.255.255.0, hostname R1

R1(config-if)#
*Mar 1 01:39:42.143: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 10.1.1.2 (FastEthernet0/0) is up: new adjacency
