NO DHCP Server?

[JoshGarmonCiscoCCNA]

when configuring a Router as a DHCP server, is that because there is no DCHP server to begin with?

or there is a Server but your hard-setting things so that the Server distributes the IP addresses THROUGH the Router?

still confused about it.

It's because you don't have any other DHCP server.

Personally I have never used a L3 switch or router for this ie. always used a dedicated server but it is an option.

Edit - if you do use a server then on every L3 vlan interface except the one the DHCP server is in you need this command -

"ip helper-address <DHCP server IP>"

which tells your L3 device to forward the DHCP request onto the DHCP server as a unicast packet.
