EIGRP - Default routes
* Like IGRP, EIGRP also does not understand 0.0.0.0 static route,
and will not automatically redistribute it. However, you can
redistribute 0.0.0.0 if present in the routing table or learned
from another source.
* EIGRP also supports "ip default-network", provided that the
network is in the routing table and is tagged D or EX. you can
not use connected routes or routes leared via another routing
source. If you want to use connected route, it must be included
in the EIGRP routing process. If you want to use routes learned
from another routing source, it must be first redistributed in to
EIGRP.
