Hello,
Could you please double check the area type comparison table in the show notes?
I think it is supposed to be more like this:
|---------------------|------|------|------|------|------|
| Standard | Yes | Yes | Yes | Yes | Yes |
| Stub | Yes | Yes | No | No | No |
| Totally Stubby | Yes | No | No | No | No |
| NSSA | Yes | Yes | No | No | Yes |
| Totally Stubby NSSA | Yes | No | No | No | Yes |~~~~
