Personally, I like the to KISS, so one big 'transit
LAN'.

ITYM two big transit LANs -- one must be prepared for a
switch to fail.


These're going to be router-to-router connections (each AR
is connected to both CRs) and I had thought about tying them
all into one VLAN vs. PTP Gig-E.  I was just trying to find
out the operational benefits of either design.
