Guys
Im trying to understand the command traffic-share in EIGRP but, I think
I came to the conclusion that EIGRP by default uses balanced unequal
load sharing using the metric to determine how many packets are sent to
which interface
Please could anyone provide more detailed information on how to modify
the DLY when you are not allowed to modify the bandwidth just to get
certain ration let say 5:1?
Thanks
Victor.
