     1  This configuration represents three nodes in a chain.
     2  n0 -> n1 -> n2
     3  
     4  The organization of these nodes isn't strict, but since n0 is only aware of
     5  n1 initially and n1 is only aware of n2 initially, they end up routing in a
     6  chain. If this were a real network they would all connect to each other in a
     7  clique. The reason this doesn't happen with this test configuration is because
     8  nodes are forbidden from connecting to multiple outbound IPs from the same
     9  group, and since all are running on localhost, they never expand beyond their
    10  single outbound peer.
