Internet-Draft Tunnel Encapsulation Attribute for UDP July 2013
1. Introduction
[RFC5512] specifies a method by which Border Gateway Protocol (BGP)
speakers can signal tunnel encapsulation information to each other
and accordingly it defines support for Generic Routing Encapsulation
(GRE)[RFC2784], Layer Two Tunneling Protocol - Version 3 (L2TPv3)
[RFC3931] and IP in IP [RFC2003] tunnel types. This document builds
on [RFC5512] and defines support for the User Datagram Protocol (UDP)
tunnel type which is applicable to at least the following two
application cases: IP-in-UDP encapsulation [IP-in-UDP] and MPLS-in-
UDP encapsulation [MPLS-in-UDP].
2. Terminology
This memo makes use of the terms defined in [RFC5512].
3. BGP Tunnel Type Code for UDP
To use either the Encapsulation Subsequent Address Family Identifier
(SAFI) or the BGP Encapsulation Extended Community defined in
[RFC5512] to signal the UDP tunnel type information across BGP
speakers, a new Tunnel Type code (TBD) indicating the UDP tunnel type
needs to be assigned by IANA.
This document does not specify any UDP tunnel specific sub-TLV.
Furthermore, the BGP Encapsulation Network Layer Reachability
Information (NLRI) Format is not modified by this document.
4. Security Considerations
The security considerations mentioned in [RFC5512] is applicable to
this new BGP Tunnel Type code for UDP tunnels as well. No new
security risk is introduced by this new Tunnel Type code for UDP
tunnels.
5. IANA Considerations
A new BGP Tunnel Type code indicating the UDP tunnel type needs to be
assigned by IANA.
6. Acknowledgements
