AD DHCP (im pretty sure this is on topic)

with a DHCP server in an ad domain, i need to understand one thing...

we have multiple vlans on the network and all will have computers on them
with different ip subnets. how do i configure DHCP scopes when this is the
case?

in other words, i need to make sure that a client on 10.64.4.x can ONLY get
an address from the 10.64.4.x scope, and the 10.65.4.x machines get
addresses from the 10.65.4.x scope. i cant see how to avoid a 65 machine
randomly getting a 64 address.

thank you

 

Hello,

do you plan to multihome the dhcp server, or will you use dhcp relay agent ?
In both case, dhcp will send a DHCP lease with an IP that match its ip
interface from which it receive the lease request, or based on the ip of the
relay agent.

Do not make global scope

 

where would the dhcp relay agent be? and how is this configured? (is it on
the switch/router that holds the vlan?)

no the server is not multihomed

 

Yes, on router, or Windows server if present on both network.

Do you have any network router or Windows server both present on networks ?

Else you may use the network's card software to use tagged vlan (multhome
the dhcp server through one network card)

 

i believe the router/switch has the relay agent... if not ill need an RRAS
server on each subnet, correct? off topic but, when the relay agent is on a
switch/router, does it have to be configured? or is it automatic when you
create the vlan?

 

Hi
In the relay agent you define wich DCHP address to contact.
