Abstract:

   Segment Routing(SR) Policies can be advertised using BGP.  An SR
   Policy may has lots of attributes, and as the application and
   features evolve, the SR Policy may need have more and more attribute
   attributes.  To avoid modifying BGP when attributes are added to an
   SR Policy, we can define a template.  The identifier and content of
   the template are defined by the receiver of the SR Policy.  The
   advertiser of an SR policy only needs to know the ID of the template.
   When advertising SR policy, the advertiser carries the template ID in
   the tunnel encapsulation information of the SR policy.  After
   receiving the SR Policy information, the receiver obtains the
   corresponding template and content according to the template ID,
   thereby obtaining abundant constraint configuration information.
