While it goes without saying that you need the same (can be 5!) number of links to each router in a multichassis LAG, what isn’t so obvious are things like port groups etc. If you have an oversubscribed platform, you might need to look at running each wire in a LAG to different port groups, and then look at things like switch ASICs and span those as well. Even try to span diverse slots/modules if you can. But 5 6 or 4 per chassis shouldn’t make a huge difference. -Ben

As others have noted, there can be implementation specific issues that you can't necessarily predict but most typically when I hear "odd vs even" discussions, usually the caveat is not a trunk but a redundant connection. Putting three links on router A and two links on router B obviously doesn't work well.

I'm asking since I heard in the past something negative about odd numbers of lag members. .but I also have heard that it's not a big deal. Let me know please
