See Text Below for Licensing Declaration
Licensing information, comments, notes, or URL for further information

If technology in this document is included in a standard adopted by IETF and any
claims of any Cisco patents are necessary for practicing the standard, any party
will have the right to use any such patent claims under reasonable, non-discriminatory
terms, with reciprocity, to implement and fully comply with the standard.

The reasonable non-discriminatory terms are:

If this standard is adopted, Cisco will not assert any patents owned or controlled
by Cisco against any party for making, using, selling, importing or offering for
sale a product that implements the standard, provided, however that Cisco retains
the right to assert its patents (including the right to claim past royalties)
against any party that asserts a patent it owns or controls (either directly
or indirectly) against Cisco or any of Cisco's affiliates or successors in title
or against any products of Cisco or any products of any of Cisco's affiliates
either alone or in combination with other products; and Cisco retains the right
to assert its patents against any product or portion thereof that is not necessary
for compliance with the standard.

Royalty-bearing licenses will be available to anyone who prefers that option.

Note: The individual submitting this template represents and warrants that he or she is authorized by the Patent Holder to agree to the above-selected licensing declaration.
