DHCP Trouble. (Question #62)
Consider three routers named HOST, RELAY and DHCP-SERVER connected as in the following topology
HOST e0 ---- e0 RELAY e1 ---- e0 DHCP-SERVER
It is seen that the HOST which is configured to obtain the IP address for its ethernet0 interface using DHCP is failing to successfully get its address. Given the following configuration for the three routers in question, can you figure out what the problem is?
HOST
RELAY
DHCP-SERVER
HOST e0 ---- e0 RELAY e1 ---- e0 DHCP-SERVER
It is seen that the HOST which is configured to obtain the IP address for its ethernet0 interface using DHCP is failing to successfully get its address. Given the following configuration for the three routers in question, can you figure out what the problem is?
HOST
interface Ethernet0
ip address dhcp
RELAY
interface Ethernet0
ip address 10.10.10.1 255.255.255.0
ip helper-address 20.20.20.2
