Hi

I am confused in regrading Eigrp load balance. please clear me my confusion.


I have Ho router which connect another BR. from Ho to Br has 3 link. example

E=HO and A=BR

· E-B-A with a metric of 30

· E-C-A with a metric of 20

· E-D-A with a metric of 45


Now my question is>


1. If I run Eigrp then by default equal load balance and with 3 link data is transfer same time to go destination Br? or only data transfer E-C-A ?.


2. If I use variance 2 then EIGRP provide unqual load blance link path

E-B-A and E-C-A.


so my confusion is at first normal eigrp run then 3 link use for data transfer to go destination A and when I want only two link use for data transfer to go destination A same time then I use Variance ?


thanks

by default eigrp do load balancing between paths with equal cost.

Hi

difference between equal and unequal loadbalance ?



1. if metric is same among the three path then it is called equal load balance ?


2. if metric is not same among the three path then it is called un equal load balance ?


Thanks
