Whoops sorry guys, it's getting late ;) I just read again what I wrote
its complete nonsense. Also tested it and it was surprising: doesn't
works as the book says.
According to theory: RIP only injects a default route using default
information originate, if it is in the routing table OR is learnt by
another protocol. (static doesn't count) Conclusion: RIP doesn't
propagate the default route if it's static. In this case use
redistribution. (CCIE exam cert guide)
I tested it (12.4) and it seems to work regardless of any static route.
Command reference also doesn't say anything about this restriction.
R5 - using default-information originate
ip route 0.0.0.0 0.0.0.0 13.0.0.222
router rip
version 2
network 31.0.0.0
default-information originate
no auto-summary
C 31.0.0.0/8 is directly connected, Serial0/1/1
S* 0.0.0.0/0 [1/0] via 13.0.0.222
=============
R4
router rip
version 2
network 31.0.0.0
no auto-summary
C 31.0.0.0/8 is directly connected, Serial0/1/1
R* 0.0.0.0/0 [120/1] via 31.0.0.5, 00:00:01, Serial0/1/1
I tried without the static route, it works also. I'm also confused
now...

Hi Kim and all,
RIP only injects a default route using default information originate, if
it is in the routing table AND is learnt by RIP.
This means if the default route is present, but is static or learnt by
other protocol, you have to use redistribute.
Cheers, Istvan

Hello All,
Any idea why other RIP enabled routers are not receiving default route
from a RIP router that has Default Information Originate configured?
Thanks.
Kim
