Sorry, Barbara, but that is not what I suggested.

The underlying properties are what is fundamental to the protocol, and
I believe they are what should be exported by the management interface.
The link classification is just something that appears in the user
interface, and gets translated into the underlying properties.

The inverse transformation is not always possible: 2-out-of-3 with split
horizon disabled does not correspond to any currently defined link type
(that particular combination would be useful for e.g. ATM networks).
