Re: [Rtg-dt-encap-considerations] Proliferation of encapsulations ...

The reason I was asking for examples was to understand whether it really
was a separate encapsulation layer (e.g. GRE) versus just running directly
over IP or Ethernet without and encapsulation (e.g. IP-in-IP).  Since you
named both, then further clarification in the text might be needed to
cover both cases (direct encapsulation and encapsulation using an
additional header).
