Abstract

This memo defines how the 6bone uses the 3FFE::/16 IPv6 address prefix, allocated in RFC 2471, "IPv6 Testing Address Allocation", [6BONE-TLA], to create pseudo Top-Level Aggregation Identifiers (pTLA's) and pseudo Next-Level Aggregation Identifiers (pNLA's).

RFC 2921              6BONE pTLA and pNLA Formats         September 2000


   The guiding specifications for IPv6 addressing relating to the 6bone
   prefix, and the pTLA and pNLA formats, are "IP Version 6 Addressing
   Architecture"  [ADDRARCH], and "An IPv6 Aggregatable Global Unicast
   Address Format" [AGGR].

   The purpose of creating pseudo TLA and NLA formats for the 6bone is
   to provide a prototype of the actual TLA and NLA formats as they
   might be used in production IPv6 networks. To do this economically,
   using only a minimum of real production IPv6 address space, a single
   TLA, 3FFE::/16, was reserved by the IANA (Internet Assigned Numbers
   Authority) for testing on the 6bone. Thus it was necessary to define
   a pretend-to-be, or pseudo, TLA and NLA structure to use under the
   3FFE::/16 prefix.

   Given the 48-bit length of the IPv6 Aggregatable Global Unicast
   Address external routing prefix (that contains the TLA...
