In the previous version of the Intro document, we had a sub-section (in the
"Initial Applications" section) titled "Local Uses" which started like this:
LISP has a number of use cases which are within purely local
contexts, i.e. not in the larger Internet. These fall into two
categories: uses seen on the Internet (above), but here on a private
(and usually small scale) setting; and applications which do not have
a direct analog in the larger Internet, and which apply only to local
deployments.
Among the former are multi-homing, IP version traversal, and support
of VPN's for segmentation and multi-tenancy (i.e. a spatially
separated private VPN whose components are joined together using the
public Internet as a backbone).
As a result of the interim, we apparently decided to break out VPN's as a
separate sub-section, because I know have a new sub-section:
Virtual Private Networks
This includes support of VPN's for segmentation and multi-tenancy
(i.e. a spatially separated private VPN whose components are joined
together using the public Internet as a backbone).
and the cryptic note "L2 and L3".
I'm really lost as to what the document should say/talk about in this
sub-section, and I'm not sure what that "L2 and L3" should expand into
(presumably it refers to both bridged VPNs at level 2, and also 'classic'
VPNs at level 3).
There doesn't seem to be a lot written about VPN support in LISP: there is
one ID ("Layer 2 (L2) LISP Encapsulation Format"), but it mostly just gives
the packet format; a quick Google search didn't turn up anything that useful
either.
Can people give me some idea what this sub-section should say? I don't need
text, just a list of points to cover. Thanks!
