Re: [lisp] LISP Overlay Model

[Luigi Iannone <[e-mail]>]

Hi All,

Thanks from the reply so far.

What I gather is that there is interest in extending the LISP overlay model to support other data-planes.

What remain unclear is what those data-planes should be. 
Note that it is impossible to cover all existing data-planes.

Would be helpful if the group gives a clearer direction by suggesting a set encaps to add support for.
(this include as well the willingness to directly contribute to the work)

ciao

L.
