In this configuration we use a router for a "host" simulation and place the port on R6 to initiate a dhcp request. Configuration : DHCP POOL CONFIGURED ON BOTH R1 and R2 ip dhcp excluded-address 192.168.1.1 192.168.1.5 ( Exclude the IP's that we do not want allocated out ) ip dhcp pool DATA network 192.168.1.0 255.255.255.0 (Define the network scope we want to give out ) default-router 192.168.1.1 ( The default router is the virtual IP that we setup for HSRP ) R1: interface FastEthernet0/0 ip address 192.168.1.2 255.255.255.0 duplex a...
