6513 multiple dhcp-pool domain-names

vpersaud001 · ‎05-07-2008

Hi,

Is it possible to add multiple domain-names in dhcp-pool config on the 6513?

In other words is this a legitimate command : domain-name abc.net,xyzoa.net,xyz.co.jp? Or is there some other way to make it work?

Thanks.

Yes, you can, but you need to set the option manually. This is assuming you mean the DHCP option for domain search suffix.

Follow this guide:

Noran... Thanks.

I need to know if you can set multiple domain search suffix for each DHCP pool.

Unless I missed it the document only shows one dhcpd domain - example.com. I actually tried to add another domain but it replaced the previous one.

Let me know if you figure this out. I'm trying to do the same thing.

No luck yet. Still working on it.

I have been toying with this in my lab to no avail. After further research i found this:

http://www.iana.org/assignments/bootp-dhcp-parameters

It makes mention of option '135' which MS recognizes as domain suffix search-order, but that doesn't mean anything. I tried a couple different variations under my test dhcp pool...

option 135 ascii "\"test1.com\",\"test.com\""

option 135 ascii "test1.com,test.com"

but none of these ever get served to my client (according to wireshark). I would lean towards this being an issue with the IOS not serving statically configured options.

Lain,

Per advice from another forum this can only be accomplished in a Windows environment via group policy.
