	I have been wondering about the pros and cons of a certain
hypothetical system configuration.  The system configuration is as
follows:

                                 __________
ETHERNET                        /          \
                   ________    /            \
-------------------|BRIDGE|---/              \
               \_  --------   |   FDDI       |
                 \            |     RING     |
                  \___        \              /
                      \__      \            /
                         \     /\__________/
                          UNIX/     
                          SERVER     

The UNIX server has both an ethernet interface and an FDDI.  Because
the network is bridged, the host has a different IP address for each
interface, but both interfaces are on the same logical subnet.  Both 
interfaces in the situation are live.  What I would like to have your 
opinion on is the following:

1) What are the benefits derived by this configuration? (i.e. redundancy?)

2) What problems would this configuration cause? (i.e. broadcast
   packets being received by the same machine on two different interfaces)

Any comments would be greatly appreciated.
