Hello Yasmeen,

you can perform load balancing at OSI layer 2 using a port channel or at OSI layer 3 (IP) using equal cost multi path ECMP.

in both cases load balancing will be flow based: a specific flow with a source IP address A.B.C.D and a destination E.F.G.H will use a single physical link in outgoing direction.

So the advantages of load balancing are clear when you have multiple traffic flows with a variety of source and destination addresses.

Hope to help

Giuseppe
