Some networks require communication between an interior and
exterior
portion of a Virtual Private Network (VPN) or through a
concatenation
of such networks resulting in a nested VPN, but have
sensitivities
about what information is communicated across the boundary,
especially
while providing quality of service to communications with
different
precedence.  This note seeks to outline the issues and the
nature of
the proposed solutions based on the framework for Integrated
Services
operation over Diffserv networks as described in RFC 2998.
