RFC Status Change : RFC 3068 An Anycast Prefix for 6to4 Relay Routers and RFC 6732 Provider managed tunnels to historic RFC 3068 introduces a "6to4 anycast address" in order to simplify the configuration of 6to4 routers. It also defines how this address will be used by 6to4 relay routers, how the corresponding "6to4 anycast prefix" will be advertised in the IGP and in the EGP. The memo documents the reservation by IANA (Internet Assigned Numbers Authority) of the "6to4 relay anycast prefix." draft-ietf-v6ops-6to4-to-historic-11.txt requests that RFC 3068, "An Anycast Prefix for 6to4 Relay Routers", be made obsolete and moved to historic status. It does so because the mechanism is considered unsuitable for widespread deployment and use in the Internet. further recommendations are made for the operations of existing 6to4 anycast services. draft-ietf-v6ops-6to4-to-historic-11 obsoletes RFC 6732 "6to4 Provider Managed Tunnels". It recommends that future products should not support 6to4 anycast and that existing deployments should be reviewed.
