Hi Obaid

See Bug 1720 <http://redmine.named-data.net/issues/1720> note-17: Our
intention is not making UDP tunnels like physical links

A "permanent face" that does not close upon failure is in the plan. It's
intended for connections between routers.
It's defined in Face Management protocol, but no face currently support
that.
Its implementation depends on tunnel authentication protocol
<http://redmine.named-data.net/issues/1285>.

Yours, Junxiao
