Operational Routing Reality - Full /32 or just /30 on Legacy Core ? The FREE 64-bit addressing using 12+18+6+24+4 can be coded using 6-bit symbols such as: LL.LLL.L.LLLL.X
The 12+18=30 are routed on legacy equipment. The Destination is Flipped and 6+24=30 is routed. This assumes /30 routing is where the legacy core reaches steady state. Any /32 features will not likely be tapped. That is because the +4 bits are carried un-flipped in the right-most bits. http://a1.twimg.com/profile_background_images/95178872/IPv4.png via http://Twitter.com/IPv3 Opinion: Anything using "Options" is a non-starter. http://www.ietf.org/mail-archive/web/ipv6/current/msg11681.html also welding UDP on gets one into the "Pseudo Header" mess. MPLS with a one-word (32 bits) Shim outside of the IP Header continues to gain favor. =================================== 00 - UNIX 01 - ISOC, IETF, IRTF, IANA, ICANN, NANOG, RIRs... 10 - IEEE, ATSC, FCC, NTIA, NIST, LEOs... 11 - UN, ITU, ETSI... =================================== _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
