RE: EIGRP Default-Information Command

What does a "show ip eigrp topo" have to say about your quad-0 route?
Is it flagged as "external" (I don't mean an admin distance of 170)?

In my experience, I've seen EIGRP handle the default route differently
when injected via a manual summary or by redistributing a static route
vs. learning it by virtue of the "default-network" command.

I've tried no default-information in and also no default-information
allowed
in under eigrp process, both still allow the default route to show up in
my
routing table.

R4 SENDING DEFAULT ROUTE TO R3. R3 TRYING TO BLOCK THAT ROUTE FROM
PLACED
IN ROUTING TABLE.

R4

 frame-relay map ip 1.1.1.3 403 broadcast
 frame-relay map ip 1.1.1.4 403 broadcast

You can also use:
R1
interface Serial0/0
 ip summary-address eigrp 1 0.0.0.0 0.0.0.0 5

This will create an internal summary default. The
router will only advertise this route out the
interface.

At the other end if you did not want to see a default
you could use the command

R2
router eigrp 1
no default-information in

e run EIGRP in our network at work and we just
"redistribute static" to propagate the golr. I
actually wasn't aware you could use default commands.
