Thanks for your reply, before i posting this post, i did search about learningnetwork.cisco and i found the link your attached as well, but that helps me in EIGRP, so how about the difference between EIGRP with others routing protocols such as RIP/OSPF used default-information originate?
The "ip default network" is different from "default information originate" and "redistribute".
Use the ip default-gateway command when ip routing is disabled on a Cisco router. Use the ip default-network and ip route 0.0.0.0 0.0.0.0 commands to set the gateway of last resort on Cisco routers that have ip routing enabled. The way in which routing protocols propagate the default route information varies for each protocol.
i dont know the reason exactly why ospf/rip use "default information originate" and eigrp not but i found this on the router which it displayed as...
which it seems like we can configure both commands on eigrp
thanks for verifying it and i get more clear about it. anyway i did post in serverfault as well. i get more clear as what those command do.
