IDR experts and the Authors of draft-ietf-idr-segment-routing-te-policy-07:

The section 2.1 of draft-ietf-idr-segment-routing-te-policy-07 describes a new SR Policy SAFI under NLRI of BGP UPDATE to advertise SR policies.

Does it mean that SR Policy SAFI is under the MP-NLRI Path Attribute (Code = 14)?


The Section 2.2 indicates that SR Policy is encoded in the Tunnel Encapsulation Path Attribute defined in the draft-ietf-idr-tunnel-encaps-12.

Does it mean the SR policy is also under the Tunnel Path Attribute with Code =23?

Can you please explain is it MP-NLRI Path Attribute or Tunnel Encap Path Attribute that SR policy are encoded?

Thank you very much.
