Detailed Description

The topology is of the form:

           __________
          /          \
 nSrc -- nA -- nB -- nC -- nDst

Following are the tests in this test case:

Test the routing from nSrc to nDst.
Test if the path taken is the shortest path. (Set down the interface of nA on nA-nC channel.)
Test if the NixCache and Ipv4RouteCache are empty.
Test the routing from nSrc to nDst again.
Test if the new shortest path is taken. (Set down the interface of nC on nB-nC channel.)
Test that routing is not possible from nSrc to nDst.
