matching vendor-encapsulated-options?

[Johan Berglund]

Dear Sirs,
I'm trying to match clients based on information in the option 43
suboptions.
My goal is to be able to send the correct filename depending on the clients
software version.
The clients are sending their current version as a option 43 suboption along
with other information.

I've played around with option spaces but that is just for send encapsulated
options _to_ the client or am I wrong?

I would like to do something like this:

option space vendor;
option vendor.swversion code 12 = text;

vendor-option-space vendor;

if substring (option vendor.swversion, 0, 9) = "Version 2" {
   filename "swversion3.boot";
}


Thanks for any help with this!

Regards,
