Exchanging Routing Information Across Provider Boundaries in the CIDR Environment
RFC 1520, “Exchanging Routing Information Across Provider Boundaries in the CIDR Environment”, is a Historic document published in September 1993 by Y. Rekhter, C. Topolcic. The canonical text is published by the RFC Editor.
Abstract
The purpose of this document is twofold. First, it describes various alternatives for exchanging inter-domain routing information across domain boundaries, where one of the peering domain is CIDR-capable and another is not. Second, it addresses the implications of running CIDR- capable inter-domain routing protocols (e.g., BGP-4, IDRP) on intra- domain routing. This memo provides information for the Internet community. It does not specify an Internet standard.
What “Historic” means
A specification that has been superseded or is otherwise no longer recommended for use.
