Eigrp bandwidth percent cntrl

[feroz syed]

Hi,

I have very big confusing in eigrp bandwitdh allocate,actually i have two eigrp topology using frame-relay switch one is hub and spoke

scenario another one is point-to-point connection from hub to spoke,

Now in first topology hub has connection with two spokes R1--R2 and R1--R3, hub using serial interface with default bandwitdh 1.544kbps and both spokes aslo the same bw.  how i have to calculate to reduce the bandwidth for eigrp to use 25% bw on hub interface, by default eigrp take 50% of bw so (1.544 /2 = 0.772  25% = 0.193kb), is this right ??, please any one make it clear for me,it would be greatly appreciated

So you have one physical interface with two spokes connected to it?

The default is to use a MAXIMUM of 50% which would be 772 kbit/s. If you set it to 25% then it would be 386 kbit/s.

It's not very likely that you have this much EIGRP traffic running though. Is this for production or labbing?

Hi, i just practice on lab, how did you get 386kbps value, it should be 0.193 ??

1544/4 = 386

193 would be 1/8 which is 12.5%
