hi:
thanks for taking your time to answer my question.
i have a question about "ip default-network" command
here is the scenario.
i tried to connect two networks without declearing one route . i thought i could use ip default network command , but it did not work out.
i thought 2.0.0.0 network is directly connected on R1 (the router in the middle) and R2 (the one one the right)
thus I just add a default route on R0 to forward and packets that do not have addresses on the routing tabel.
i also tried to add default network command on R2 ,but still it failed .
any suggestions ??? i really want to know how to use " ip default-network" make it work .
packet tracer file is attached.
please help.
