Hi again, Thx. to both of you, solution one was my favorite too. :) The PING-check you (Jeff) mentioned is new to me (as so much other stuff), sounds interesting. Greetings from Austria …

The switches will do a check (I'm guessing it's a ping) before handing out an IP address. But why run the risk of an accidental duplicate address.

You know that in real life you probably wouldn’t do it the second way, especially considering conflicts could occur (yes, I know the lab isn’t real life). The argument here is that I don’t like to leave anything to chance in the lab and you don’t want to be troubleshooting a self-inflicted DHCP/IP conflict issue on top of everything else you’re already doing. It’s slightly more configuration work, but because IOS doesn’t offer a DHCP clustering/LB mechanism, I’d just split the pools. Justin From:[email protected]<mailto:[email protected]> [mailto:[email protected]<mailto:[email protected]>] On Behalf Of Michael Ruetz Sent: Tuesday, January 07, 2014 21:45 To: [email protected]<mailto:[email protected]> Subject: [OSL | CCIE_Wireless] DHCP on IIOS Dear Wireless-Guys, I though about setting up a redundant DHCP-Service running on two IOS-Devices while preparing for the lab (in march), and came up with two solutions: — split the DHCP-pools in half on the two boxes — configure both devices with the same (!) pool of addresses, and leave it to the client’s duplicate-adress-check to resolve any issues Any recommendations from your side would be very welcome.
