EIGRP IP Bandwidth-Percent

Lessons Discussion

Hi Rene,
I am confused with multipoint scenario.

  1. “When you run EIGRP over a frame-relay multipoint network then EIGRP will divide the bandwidth of the physical interface by the number of EIGRP neighbors.” Let’s assume that we have hub router with physical bandwith of 1544kbps and 4 neighbors, so 1544/4 =386. Is this correct that maximum CIR on our PVCs can’t be greater then this value?

  2. In your scenario you configured only a hub router with bandwidth 256 subint command. That’s how I see it: Spoke 3 with CIR 256kbps on PVC3 still will be sending EIGRP traffic up to 128kbps(256/2), but on the hub router there will be a queue with eigrp traffic, since it can only send 256/4 * 50%=32kbps. Am I correct?
