Re: EIGRP Loadsharing

Ron/Ravi...

As I gone thew the link which you provided.. .. I have doubt here .. How
the RATIO is calculated ?? as the per the example per topology.. He used
Variance 5 , and now the ration is 80:23 .. How this 80:23 comes into
picture.. ??

Lets say .. If I want the ratio of 123:35 , then wat will be the
VARIANCE .. How can I calculate that ... ???

I am sorry .. hitting my brain to understand.. :-) .

Help me ....

Thanks...

Let's look at an example regarding unequal cost load balancing. Our goal
is to perform unequal cost loadbalancing at a ratio of 5:1 between the two
paths. R1 has two paths to the 164.1.26.0/24 network in the above
topology.
Path 1 - R1 > R3 > R2 > VLAN 26
Path 2 - R1 > R2 > VLAN 26
By default, EIGRP will choose the path with the lowest metric. For this
topology, the Point to point link between R1-R3 is 1.536 Mbps, frame-relay
link between R2-R3 is 1.28 Mbps and the frame-relay link between R1-R2 is
256Kbps. In this scenario, R1 will choose Path 1 to reach VLAN 26. At this
point if we configure the variance of 5, then the traffic will be load
balanced between the two paths at a ratio of 80:23 as shown in the output
below
