Problem: 
(i) Compare the functionality of n-port bridges with two-port bridges. 
a. Can every configuration built with n-port bridges be build with
two-port bridges?
 b. Suppose a topology consists of n LANs interconnected with a single
n-port bridge. In that topology a packet always requires a single hop
to get from any LAN to any other LAN. Can the same be accomplished
with two-port bridges only? What is the minimum hop configuration of
n-LANs interconnected with two-port bridges?
(ii)In a networking environment where bridges are used as the
interconnecting devices, how is it possible for a destination to be
reachable by source routing but the source routing path to be much
worse than the spanning tree path?
