Technical Summary RFC 5512 defines a BGP Path Attribute known as the "Tunnel Encapsulation Attribute". This attribute allows one to specify a set of tunnels. RFC 5512 states that the attribute is only carried in BGP UPDATEs that use the "Encapsulation Subsequent Address Family (Encapsulation SAFI)". This document deprecates the Encapsulation SAFI (which has never been used in production), and specifies semantics for the attribute when it is carried in UPDATEs of certain other SAFIs. This document adds support for additional Tunnel Types, and allows a remote tunnel endpoint address to be specified for each tunnel. This document obsoletes RFC 5512. Since RFCs 5566 and 5640 rely on RFC 5512, they are likewise obsoleted. Working Group Summary This document has had a long life in the idr WG, including two WGLCs that have resulted in discussion and updates to the document. Subsequent to the second WGLC, further issues were reported by implementors (this is why IDR has an implementation requirement!). Document Quality Implementations are recorded here: https://trac.ietf.org/trac/idr/wiki/draft-ietf-idr-tunnel-encaps%20implementations Personnel The document shepherd is Sue Hares. The responsible AD is Alvaro Retana.
