Representation of IP Routing Policies in a Routing Registry (ripe-81++)

This document was originally published as a RIPE document known as ripe-181 but is also being published as an Informational RFC to reach a larger audience than its original scope. It has received community wide interest and acknowledgment throughout the Internet service provider community and will be used as the basic starting point for future work on Internet Routing Registries and routing policy representation. It can also be referred to as ripe-81++. This document is an update to the original ‘ripe-81’[1] proposal for representing and storing routing polices within the RIPE database. It incorporates several extensions proposed by Merit Inc.[2] and gives details of a generalized IP routing policy representation to be used by all Internet routing registries. It acts as both tutorial and provides details of database objects and attributes that use and make up a routing registry.
