Network Working Group R. Callon Request for Comments: 1069 DEC Obsoletes: RFC 986 H.W. Braun UMich February 1989 Guidelines for the use of Internet-IP addresses in the ISO Connectionless-Mode Network Protocol Status of This Memo This RFC suggests an addressing scheme for use with the ISO Connectionless Network Protocol (CLNP) in the Internet. This is a solution to one of the problems inherent in the use of "ISO-grams" in the Internet. This RFC suggests a proposed protocol for the Internet community, and requests discussion and suggestions for improvements. Distribution of this memo is unlimited. This memo is a revision of RFC 986. Changes were made in order to allow the addressing used in the CLNP in the Internet to be potentially useful for routing in the context of new inter- and intra-domain routing protocols, and in the context of large numbers of networks and routing domains. The addressing scheme proposed in this RFC allows individual routing domains to make use of internal routing algorithms utilizing a variety of addressing formats, while still providing for a common addressing approach for use by inter- domain routing. These features are important due to the rapid growth currently being experienced in the Internet. 1. Objectives The data communications protocols currently emerging out of the international standardization efforts warrant an early integration into the existing extensive Internet network infrastructure. The two possible approaches are a top-down one, where ISO applications like FTAM, X.400 and VTP are integrated on top of the transport function of the IP protocol suite, or a bottom-up approach where the whole ISO tower gets integrated without merging the two suites. The bottom-up approach may make use of the fact that the ISO-CLNP and the IP are very similar in function. This implies that it is reasonable to implement a multiprotocol function in some or all of the Internet gateways (potentially including part or all of the Internet environment). The result would be that at least large portions of the Internet, in particular the backbones, can become usable for full implementations of the ISO protocol stack. A major problem with this approach is that there are open issues with Callon & Braun
