We don't currently have official support for the vendor-specific relay
agent sub-option.  For now you could either configure sub-option 9
specifically as a string of octets in hex;

# Scope globally:
    option agent.vendor-specific code 9 = string;

# Scope client-locally assuming option 2's contents are '10.0.0.1';
    option agent.vendor-specific 00:00:60:b5:06:02:04:0a:00:00:01;

Or you can navigate the new syntax (in 3.1 if memory serves) to
define option 9 as an encapsulation of an intermediary space, and
then define the enterprise-ID's as encapsulations of a space
specific to each vendor's enterprise #.

It's a lot harder to provide an example in that case.
