After going over EIGRP, I ran into offset lists which allow the modification of the metric of routes advertised by EIGRP and provide the option of traffic engineering.
I am not very experienced with traffic steering/engineering yet. May I know, is there an example where we would want to steer traffic/modify the path a packet is taking throughout the routing domain? After all, if we are running dynamic routing protocols, shouldn't they automatically determine the best path for the traffic for every destination?
Thank you in advance for your help.
