A large international ISP has hired you as one of their network engineers. The ISP still has a fairly large customer that is using an older frame-relay network. All of your colleagues are too busy working with MPLS and you are the only one who is capable of fixing frame-relay problems. The ISP wants you to look at the frame-relay network because there have been some congestion problems with EIGRP. It's up to you to configure the most optimal settings!

Hi Rene,
I'm actually going to take my CCNP ROUTE in a couple of weeks, and I remember seeing this type of question in a practice test. So, just want to check that my belief if correct..aside from setting the obvious CIR bandwidth on the spokes, the hub Bw should be set on the physical interface, and the value is 512 ?
Great labs by the way, really Cisco exam style.
Hello Bogdan,
Thanks for your comment, glad you like the labs! 
About EIGRP and frame-relay bandwidth...it depends on your setup:
1. Point-to-point sub-interfaces
2. Point-to-multipoint interfaces
3. A hybrid solution (this lab) where you mix point-to-point and point-to-multipoint.
I would highly suggest taking a look at this Cisco article that describes all methods:

Let me know if that helps you ok?
Rene
Would it be possible to to come up with a video solution? I understand that we are using both point to multi-point and point to point configuration since we have a spoke with a different speed, however router Tillburg I assume has a dedicated T1. so what do we do with the left over bandwidth?
I think I will record them this week...stay tuned 
Hoi Rene,
Can you come with the video solution or final configs?
Alvast bedankt,
Marco
Hoi Marco,
Als het een beetje meezit neem ik ze deze week op
Groeten Rene

etc....
If we decide to go with point-to-multipoint, as I understand the bandwidth set on Tilburg will have to be 128*4 (where 128 is the lowest bandwidth).
On each of the spoke routers we can set the correct bandwidth, given by the exercise, but we also have to limit the actual bandwidth used by eigrp. This value should be the same in both directions. The bandwidth used for eigrp on Tilburg is 128*0.50 = 64K ( 50% of bandwidth is used for eigrp, I always thought it was 75%, but never mind).
So If we set the bandwidth on Paris to be 256, then in order to use 64K for eigrp we need to use the bandwidth-percent command set to 25 (64/256=25).
Please correct me if I am wrong, because I always find these exercises confusing.
