Learning Objectives
• Review basic configuration of EIGRP on a serial interface
• Configure the bandwidth-percent command
• Configure EIGRP over Frame Relay hub and spoke
• Use EIGRP in non-broadcast mode
• Enable EIGRP manual summarization in topologies with discontiguous
major networks

This is very common in the corporate work enjoy

i'm not sure why i can't open your .net file, maybe need a little bit of modification.

but i did almost same lab as your topology, everything work fine except R2(East) network(loopback) didn't show up in R3(West)



R1


R2


R3

Hey

R1 Uses the Split Horizon Rule on ITs Serial Interface

Try This Command on THe Serial INt

no ip split-horizon eigrp AS

I Had the Same Problem But With THis Command it Was Resolved

Hope This Will Help

hi,
could someone please help me,
I did all that, and I also diabled the split-horizon and the routes showed up in all the routeres
but the problem is that I can not ping the loopback interfaces from one spoke to another, I can ping them both from the hub , and both the spokes can ping the loopback interfaces on the hub, but not on eachother.

I am pasting the routeing table of my hub and then the two sopks here:

this was the hub, and here is the spoks:

and the other one:

oh and also I did not place a broadcast statement at the end of my frame map ip ... command and instead I hard coded the neighbors, the adjacencies formed and all was fine about that, I just thought I should say that :-)

I have tried running this example and when I do the CPU shoots to nearly 100%
and stays there until I stop all devices.

What can I do to find out where the issue is ?

Have you assign idle-pc for the IOS image? If you have, you need to repeat changing the idle-pc until you find the one that will not use too much CPU. Also, idle-pc is assigned for each IOS image, not for each device.
