I went through and did this RIF again, and here is what I got...
The RIF is 1290.0011.1f41.0022.3001.0342.2f23.0031.f000
The RD is 1290, or 0001 0010 1001 0000...
Broken down that is
RIF type - 000 - Directed Frame
RIF Length - 10001 - 18 bytes
RIF Direction - 1 - Right to left
Max Frame Size - 001 - up to 1,500 bytes
Next I followed the RC's...

As you'll notice, I did exactly what Fred said and used the bridge numbers
to the left rather then the ones to the right (if you go through the
numbers, you'll see what I mean).
As a last thought, when I wrote this I was focused on figuring out how
right-to-left works, and I may have violated the rules about ring/bridge
numbers. I'll take a look at it tonight, but in the mean time, I'm sure
someone will point out any errors... J
By the way, you can find the original RIF document this came from at
www.laganiere.net. If I need to make changes to fix any errors I'll
increment the version number before I republish.
Hope this helps...

Subject: Re: RIF, please help
Kris: When the direction bit is set to 0, and the last bridge/ring
combination is
05d0 then that is read as destination ring 93. When the direction bit
is set to 1 ring 93 is the source ring and you use the bridge to the
left as the first bridge. For example, if the last two ring/bridge
pairs are 0a01 05d0 and the direction bit is set to 1, then the path is
read as ring 93 bridge 1 ring 160.
