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 > On May 16, 2018, at 3:48 PM, Wayne Bouchard <w...@typo.org> wrote: > > 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.
