Hello Maxborodin

Take a look at the following posts that talk about load balancing across an EtherChannel link in more detail:

Etherchannel on Cisco IOS Catalyst Switch

Hello Po When we talk about load balancing between physical connections of etherchannels, we must use some criteria to determine which physical link a particular frame will go over. Take a look at the following diagram: [image] Devices in Network A will be communicating with devices in Network B. Each of the frames traversing the link will have a source and destination MAC, and at Layer 3, will have a source and destination IP address. Remember first of all that load balancing must be emp…

Etherchannel on Cisco IOS Catalyst Switch

Hello Po Let me explain with an example. If we have this topology: [image] …and there is traffic going between all of the hosts on the left and the server on the right, then all traffic in both directions will have: source and destination MAC addresses of the hosts and of the server. source and destination IP addresses of the hosts and of the server. In this case, src-ip for Network A to B (IP addresses of the 60 hosts) and src-mac for Network A to B (MAC addresses of the 60 hosts) will …

Etherchannel on Cisco IOS Catalyst Switch

Hello Giovanni In order to know which load balancing algorithm is best to use for your particular situation, it must be made clear that each algorithm must be applied in a particular direction on the etherchannel. And this direction will also affect the choice you make. For example, take a look at the following diagram: [image] This is a network with many hosts on Network A, and only one host (the edge router) on Network B. The edge router is the default gateway for all of the hosts on Ne…

I hope this has been helpful!
