Sanjay,Ben
we had lot of discussion some time back on the same topic.U can find all
arcives also.Any way fro simplicity I will give the key-points to be
observed...
1.Ip default-network <n/w> the n/w address mentioned here should be
classfull one.If U specify any submnetted n/w address it takes as static
route.
This holds good for any n/w connected or dynamically learned.
2.Since U might be using subnets of the same n/w somewhere else U may wanted
to use ip classless ,so that U can ping properly.
3.Once ip def-n/w command is issued check for the same route as candidate
default in that router.
4.Then try to run IGRP on that n/w either by redistributing connected or
dynamic routing protocol through which U learned it.
5.Write an access-list to permit the same def route and associate it with
default-information command under router igrp in out direction.
Now U should see the default route in all IGRP routers the same def route.

Subject: RE: Default Route in IGRP

Hi,
I tried the "ip default-network X.X.X.X" where X.X.X.X was the connected
network between R2 and R3. This did not inject a default route into R1. A
static route appeared in R2 instead.
However I later tried "ip default-network Y.Y.Y.Y" where Y.Y.Y.Y was a route
learned by R2 through OSPF and this did inject a default route in to R1.
The documentation says that this should have worked even in the first case
(connected network).
Can anyone else throw some more light on this?
Thanks
Sanjay
Hello All,
I have IGRP redistributing into OSPF just fine. VLSM <--> FLSM. Now I want
to distribute a default route into my IGRP domain from the ASBR as follows:
R1------------R2---------R3--------R4
|---IGRP-----|-----------OSPF------|
At R2, I am trying to add the "ip default-netowrk X.X.X.X"
command and the external route is not being forwarded to R1. Can you help?
Thanks,
Ben Rife
