Subject: [rbridge] Use of the term "campus"

Yes, that is the usual meaning of "campus" as a quasi-generic
term.  One could argue that this dates back to using the term
campus as equivalent to site.

Because we're talking exclusively of device-relative topology
- as opposed to location-relative topology (geography?) - we
can agree to discount the use of the term "campus" as it might
apply to buildings and sites.

The problem is that a lot of "stuff" is defined around the way
that we've used the term "campus" in this (TRILL) context.  If
we define it a different way, or decide to use a different term,
that's fine with me.  I just have to change a lot of text around
other terms such as -

CTT - Campus Transit Table
CFT - Campus Forwarding Table
CFT-IRT - Campus Forwarding Table - Ingress RBridge Tree

- as well as a lot of textual descriptions and places where we
just use the derived acronyms (assuming the "new" term doesn't 
start with a "C").

Actually, I'm disappointed that we're having this discussion
again - and doubly so because I'm the one that had to bring it
up.
