The DEC LanBridge problem is an old one, isn't it?
The old firmware on LanBridges would "learn" the broadcast address
if it heard it, and add it to the "routing" table.  Unfortunately,
this was also the flag for the end-of-routing-table marker, so the
table stopped growing to boot!  (atleast these are my recollections)

DEC has supplied updated "firmware" with the bug fixed.  
There was considerable difficulty dealing with field service
(convincing them that a repair was called for, that the repiar
part number I gave them was real, etc, etc, etc).  They eventually
did fix our LanBridge 100s.  But then we went on to upgrade our
network, and replace LanBridges with P4200s.  Now, instead of
10,000 packets per second, we get 1000 :-)

If nothing else, when the LanBridges work, they're fast!
