How to setup DHCP at one site to service clients at branch locations

Posted on 2004-04-29

I have a DHCP server at a location called "5"

The scope is configured as 10.x.1.1 to 10.x.2.1 where "x" is the campus number.  The mask is /20

This works just fine....

Now, the question is...I want to add locations "1" to "4" and have them receive addresses from the DHCP server at location "5".

The locations are connected via Extreme layer 3 switches.

I want to be able to assign a scope, say to location "4", and make it to and make sure that computers at that location receive one of the 10.4 addresses.

Can this be done?  How?

You need to configure your Extreme Layer3 switches as dhcp relays

the ideea is that the switch will receive the broadcast from the client and forward it to the dhcp server in the name of the client.

thanks for the link to page 182....

I'm going to test it, but I want to make sure that site 4 gets a 10.4 address, while site 3 gets a 10.3 address from the dhcp server.

Will it just "know" to do this if I set up the scopes with those ranges?  How does the client know which scope to "pick from"?

Yes, it will work like this, because the dhcp will receive the "broadcast" from a relay within the scope

I've configured on nortel layer 3 switches, but it's the same, a layer 3 switch doing dhcp relay
