was reading under the heading "Route
Tagging".Uder the same,it mentions as below.In that,what is meant by bit
flags for default routing means and how it is useful or what is its
significance.Thanks for the help.

External routes are tagged with the following information:

   -

   The router ID of the EIGRP router that redistributed the route.
   -

   The AS number where the destination resides.
   -

   A configurable administrator tag.
   -

   Protocol ID of the external protocol.
   -

   The metric from the external protocol.
   -
