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!).
