Help Please: PPP Multilink

I'm going to try something a little different for this post.  Usually I take something that I've been labbing that I find interesting, or challenging, and document it for memory retention and your reading enjoyment.  This time I've got a config-let for PPP Multilink that I found quite by accident that I don't know is "right" or not.  It works, so that would mean it's right enough, but I'm hoping that someone out there can point me at some supporting documentation that can clarify what the difference is between this method and what I'll call the more traditional method, and why you would use one over the other.

Assigning Addresses over PPP using DHCP

This topic is something that seems to kick my ass every time I need to configure it.  For some reason I can easily remember how to set up PPPoE, and I can remember how to dynamically assign addresses to the clients using IPCP without issue.  But for some reason I have a real mental block when it comes to using DHCP instead.  To that end, it’s time to blog it!
