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
additional information used to create a tunnel and the corresponding
encapsulation header, and 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 have the "Encapsulation Subsequent
Address Family (Encapsulation SAFI)". This document updates RFC 5512
by deprecating the Encapsulation SAFI (which has never been used),and
by specifying semantics for the attribute when it is carried in
UPDATEs of certain other SAFIs. This document also extends the
attribute by enabling it to carry additional information needed to
create the encapsulation headers additional tunnel types not
mentioned in RFC 5512. Finally, this document also extends the
attribute by allowing it to specify a remote tunnel endpoint address
for each tunnel.
