You use a different CD pair for each bunker. It's easy enough

Easy enough to generate the CD's. Key distribution & syncing up could
be a bit problematical though. Solveable, but non-trivial.

Syncing should be easy enough, include a station ID/date header at
the front of every message and let a computer start scanning key
blocks until beginning of the message results in a valid ID header and
go from there. Worst case scenario is that the computer checks all
700,000 key blocks and doesn't find a match because the wrong disc was
used; however the operator should notice that something is wrong long
before this.
