Hi @Steven Williams ,

What is the different between L2Out and L2Extension in ACI?

---

First the simple answer

L2Out=Bad Idea

L2Extension=Good Idea

Now in pictures

L2Out

L2Extension

And finally, a sensible answer

Whatever you can do with a L2Out (which is to map a single VLAN to a single EPG) can be done by L2Extension, and done

• more easily
• more flexibly
• with more options

L2Outs are complicated, and I'd never recommend using one.

I hope this helps
