HI,
I've tested this just now and didn't have any problems. I found that
aslong as there was a route in the routing table toward the network
I'm pointing to with the "ip default-network" command things work ok.
I did find however that I needed to enter the command with a classfull
ip address otherwise it would simply convert my command into a static
route. (11.3.9T)
Also the rule of split-horizon applies, If I have routers A--B--C and
place the "default-network" command on A pointing to a network hanging
off C the candidate route is tagged in A's routing table but no
propagated as a default router to B or C.
I'm also trying to understand what use the "default-information
originate" is with rip. It doesn't seem to have any effect with either
a "default-network" or "ip route 0.0.0.0 0.0.0.0 x.x.x.x"
Why & how would I use "default-information originate" under rip??
Thanks,
Philip.

Subject: RIP default routes
Hi Group,
I am going through Jeff Doyle book on pg. 755. In his case study using
"ip default-network command" for rip routing, he stated that the
router that source the default route does not have to its gateway of
last resort set for it to advertise the candidate route out.
When I tried his example I have the following error:
04:59:09: RT: 1.0.0.0 is now exterior
