I understand that for a routing protocols to advertise a default route to its neighbors using the "default-information originate" command, ISIS, EIGRP, OSPF (unless using the always keyword) and BGP (requiring further redistribution) needs a default route to already exist in the routing table before advertising a default route through that command, can any one confirm whether RIP requires valid default route in the routing table before originating the default route using this command or not ?
I've confirmed what you've said but with only one thing to add; Normally, exterior/default routes are always accepted and default information is passed between EIGRP processes when redistribution occurs. when doing so, we still need to confirm the following command to either allow the sending or receiving of a default route (should be there by default):
allowed Allow default information
in Accept default routing information
out Output default routing information
Note: The default network of 0.0.0.0 used by Routing Information Protocol (RIP) cannot be redistributed by IGRP but can be redistributed by EIGRP.
