6to4 Provider Managed Tunnels (6to4-PMT) provide a framework that
can help manage 6to4 tunnels operating in an anycast configuration.
The 6to4-PMT framework is intended to serve as an option for operators 
to help improve the experience of 6to4 operation when conditions of the 
network may provide sub-optimal performance or break normal 6to4 
operation. 6to4-PMT supplies a stable provider prefix and forwarding 
environment by utilizing existing 6to4 relays with an added function of 
IPv6 Prefix Translation.  This operation may be particularly important in 
NAT444 infrastructures where a customer endpoint may be assigned a 
non-RFC1918 address, thus breaking the return path for anycast-based 6to4 
operation.  6to4-PMT has been successfully used in a production network, 
implemented as open source code, and implemented by a major routing 
vendor.  This document is not an Internet Standards Track specification;
