Submission of topology maps

Scope of document

This document explains why any member might be asked to present a topology map of their network. The document also describes the map details which the RIPE NCC expects from the member. We have a sample IPv4 network topology diagram here and an IPv6 network topology diagram here.

What is a topology map?

A topology map is a graphical representation of how a proposed network will look like at the IP level. For IP Resource Analysts (IPRAs), a topology map can be useful to understand the request, especially large ones. If the information submitted in a request appears unclear then it may well be the case that the IPRA handling the request may ask the requester to submit a relevant topology map. A good topology map can significantly speed up the processing time of a request. As a result of the increasing number of requests which need the help of a topology map to fully evaluate them, the RIPE NCC has decided to come up with a set of standards for Local Internet Registries to follow when submitting them both to help the requestors and to ensure that we apply the same procedure to all LIRs.

Guidelines for the Submission of Topology Maps:

The topology map should reflect information already presented to us in the relevant sections

of the European IP Address Space Request form, such as the addressing plan template

Depending on how the proposed network will look like, the IPRA concerned

may ask for a breakdown of a sample node or POP. Depending on the scale of the request, you may further be asked to fax us a copy of purchase orders.

The topology map is used to help us understand your request so please use as many

details as possible, this may include line speeds, something which we have not shown in our example.

When showing items, for example dial-in ports or routers then you should specify the

manufacturer’s name and relevant model number.

Requestors may use the symbols already provided in the example topology map

such as routers and dial-in ports.

Topology maps showing a strong resemblance to the one on our web site will not

be accepted!

The example IPv4 and IPv6 topology maps are designed to show the kind of depth

and detail which we expect to see.
