EIGRP POINT-TO-POINT BANDWIDTH PACING
WRITTEN BY RENE MOLENAAR ON�29 AUGUST 2011. POSTED IN�EIGRP
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. Whenever router Tilburg is sending major�EIGRP�updates there are problems with congestion. Think you can tune EIGRP so this network won't have congestion anymore?
* All IP addresses have been preconfigured for you as specified in the topology picture.
* Every router has a loopback0 interface:
Tilburg: 220.127.116.11 /24
NewDelhi: 18.104.22.168 /24
Berlin: 22.214.171.124 /24
Paris: 126.96.36.199 /24
NewYork: 188.8.131.52 /24
* You are not allowed to make any changes to the frame-relay configurations.
* In this topology you can see 4 spoke routers but in reality there are 10 spoke routers. I didn't add them all to save CPU power when you run this topology. Each PVC has a CIR of 64kbps.
* Router Tilburg has a serial interface 0/0 that only has a physical bandwidth of 256kbps.
* Configure EIGRP AS 1 on all routers and make sure you have full connectivity.
* Whenever router Tilburg sends EIGRP updates to all spoke routers there is congestion because the physical bandwidth of serial interface s0/0 is only 256kbps.
* Configure your network so the bandwidth reflects the CIR on the PVCs and EIGRP will only use 50% of the CIR.
