Points to discuss:

   * building organization

   * spanning-tree stuff


---+++ Where to Store network diagrams 
For "www.cs" access store PDF files in "cscf.cs.uwaterloo.ca:/autofs/www/cs/cscf/cscfnow/diagrams/networking" (sftp://cscf.cs.uwaterloo.ca/autofs/www/cs/cscf/cscfnow/diagrams/networking might work in a Linux desktop fire-browser). The directory is owned by dhergott and group writable by the www_cscf group.

The CS network core consists of four HP 5600 routers interconnected in an almost-complete graph (only one link is missing).  The connections are formed with /30 point-to-point networks, as follows:
