So, are you saying that 172.16.1.0;172.16.1.4;172.16.1.8 are not external to
R10, but external to R4? is that right?
could you show me the R10' routing table?

thanks

JP

JP,

I agree with what Rajeev has mentioned...
In fact was curious and tried it out once again and
seems to work as the Doc explains.Let me know if what
u are looking at is different in any way.

My Scenario and config are as follows:

   R5-------------- r4----------------r10--loopbacks
     e0 e0 s0 s0

--------------------
r10#show runn

Hope this helps and let me know.What are ur findings ?
I tried this with RIP on R10 to introduce same routes
into EIGRP and it works fine.

Good luck,
Annu

Thanks in advance for ur time and replies.
