hai...... actually there is a command "IP DEFAULT-NETWORK <network number>" in the router to mention the default route via it's routing protocol.....the problem is that in some websites they have told that it should be configured in "GLOBAL CONFIGURATION MODE " of the router.... but in some other sites they have told that it should be configured in "INTERFACE CONFIGURATION MODE"......so i need a help from u. which is the correct one.......thanks in advanz.......
