Subject: [Idr] Last Call: <draft-ietf-idr-tunnel-encaps-18.txt> (The BGP Tunnel Encapsulation Attribute) to Proposed Standard

The IESG has received a request from the Inter-Domain Routing WG (idr) to
consider the following document: - 'The BGP Tunnel Encapsulation Attribute'
<draft-ietf-idr-tunnel-encaps-18.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2020-10-01. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract

RFC 5512 defines a BGP Path Attribute known as the "Tunnel
Encapsulation Attribute". This attribute allows one to specify a set
of tunnels. For each such tunnel, the attribute can provide the
information needed to create the tunnel and the corresponding
encapsulation header. The attribute can also provide information
that aids in choosing whether a particular packet is to be sent
through a particular tunnel. 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 also provides support for
specifying fields of any inner or outer encapsulations that may be
used by a particular tunnel.

This document obsoletes RFC 5512. Since RFCs 5566 and 5640 rely on
RFC 5512, they are likewise obsoleted.
