Dave, you are correct, the network statement must be added to the interfaces
for participation, but know my question would be, IT's correct to have the
loopbacks participating in EIGRP?

Asunto: RE: eigrp summarization
I believe in the original configuration, Victor, that the loopbacks were
not covered in the range, as Lim wanted to do. Therefore, he cannot
summarize what he is not advertising in the first place. Please correct
me if I am missing something.

Dave, Has any sense to send eigrp packets via the Loopbacks that covers
that
range?

Asunto: RE: eigrp summarization
Lim - Did you mean to include only the Serial 0 in the routing process?
You may want to try this again with taking out the authentication and
using:
router eigrp 1
network 140.10.0.0 0.0.255.255
no auto-summary
