Adding attributes to Access-Reply

[matt.southward at gmail.com]

Forgive me if this is an obvious thing...I've been looking at the
documentation and it just isn't clicking for me. I need to send the
Framed-IP-Address and the Service-Type attributes in the Access-Reply. In
my post-auth section of my default file I've added update reply {
Service-Type = "Framed-User" }. How do I specify the Framed-IP-Address?
This value will be returned from a SQL query, if there is no value default
to 255.255.255.254.
