- Requirements for enterprise/ISP grade "Layer 2 switch" equipment Mandatory support:
Router Advertisement (RA) filtering [RFC4862]
Where this should be probably be a requirement for RFC 6105 which actually is called "IPv6 Router Advertisement Guard".
this sounds much more like a content update than an erratum to me. Fixing a - hypothetical - RFC number typo might be an erratum.
No, this really is a typo in the RFC number. The intention is that 'Router Advertisement (RA) filtering' is mandatory. The meaning stays the same, but the RFC number is a typo.
It is quite a radical change, but I do think that one of the authors already confirmed this really was a mistake. But maybe Jan or Sander can give more details.
But I'm with Daniel here in "let's first get a list" and wonder if this really is the only one or wether there are others.
This is the only typo that we know of, and many people have looked at this document. We have has requests for other changes as well, but I agree that those are out of scope now. This typo has been known since when the document was just published. That was almost a year ago... Can we now please just fix the damn thing? Thanks, Sander
