Re: [address-policy-wg] New Draft Document: De-boganising New Address Blocks
by Michael.Dillon＠radianz.com 26 Feb '04

>The RIPE NCC has prepared a draft document titled "De-Bogonising New >Address Blocks": That is a misleading title. The problem is that ISPs cannot react quickly enough to open filters when new ranges are allocated. The proposed solution is to provide advance notification. I suppose this could allow ISPs to open filters before the new addresses are actually in use officially. However, it will also allow spammers to announce this space and get it through bogon filters. The real solution to this problem is to make it possible for ISPs to closely track RIR allocations in their filters in a semi-automated way. There may still be a few days of delay before a new allocation is fully routable but ISPs can compensate for that with internal processes. Why can't ISPs subscribe to a feed of all new RIPE allocations in near real-time? --Michael Dillon

Proposed change 2004.1: extended route creation rules
by Engin Gunduz 16 Feb '04

16 Feb '04

Dear colleagues, [apologies for duplicate mails] Some time ago, Frank brought an issue regarding route object aggregation to our attention in the DB-WG mailing list. Please see the short thread at: http://www.ripe.net/ripe/mail-archives/db-wg/2003/msg00474.html http://www.ripe.net/ripe/mail-archives/db-wg/2003/msg00475.html We have prepared a proposal to extend the route object creation rules to resolve this issue. However, the resulting proposal turns out to be quite complex as it builds on the current route object creation rules, which are already complex enough. Considering that the need for route object aggregation is encountered very rarely, it might not be worth implementing it. After the deployment of version 3 of our whois software, we have seen only a couple of such cases. In those cases, we have resolved the issue by applying the rules that we specify below manually. I would like to ask the working groups if they think this proposal is too complex. Implementing it would not be a problem technically, but I'm more concerned about explaining the complex rules properly to the users of the whois database. Best regards, and thanks for your time, -- Engin Gunduz RIPE NCC Software Engineering Department ============================================================= A PROPOSAL FOR EXTENDED ROUTE OBJECT CREATION RULES This document is about being able to create route objects that aggregate inetnums/route objects. This is needed where a user cannot merge two or more inetnum objects into one larger inetnum object, but still needs to create a route object that aggregates these inetnum objects. This is seen especially with assigned PI inetnum objects. A hypothetical example: Suppose there exist the following two inetnums in the whois database: inetnum: 12.0.0.0 - 12.0.0.255 netname: EXAMPLE-PI descr: Example Banking PLC admin-c: AA1-RIPE status: ASSIGNED PI inetnum: 12.0.1.0 - 12.0.1.255 netname: ANOTHER-EXAMPLE-PI descr: Anotherexample Printing Industries NV admin-c: ZZ1-RIPE status: ASSIGNED PI These are assigned to different end-users. Further suppose that they coincidentally take service from the same Internet Service Provider. The Internet Service Provider will want to aggregate these two assignments into a single 12.0.0.0/23 route to be announced, rather than announcing two separate prefixes, in order to keep the number of prefixes in routing tables to the minimum. However, the Internet Provider will not be able to create a single route object in the RIPE Routing Registry which implements RPSSec RFC (RFC2725). This is because the inetnum object that contains the 12.0.0.0/23 prefix will be inetnum: 12.0.0.0 - 12.9.255.255 netname: EU-ZZ-000000 descr: block for PI assignments descr: maintained by RIPE NCC country: EU remarks: These addresses are assigned to network operators. The RIPE NCC does not operate any networks using address space from this block. An explanation of how to find the correct contacts is available at <http://www.ripe.net/nicdb.html> admin-c: CREW-RIPE tech-c: CREW-RIPE tech-c: OPS4-RIPE status: ALLOCATED PI mnt-by: RIPE-NCC-HM-MNT mnt-lower: RIPE-NCC-HM-MNT changed: hostmaster(a)ripe.net 20030731 source: RIPE Note the "mnt-lower:" attribute that has RIPE-NCC-HM-MNT. See http://www.ripe.net/ripencc/faq/database/qa4.html#5 for a graphical representation of the current route object creation rules. Proposal: To address this problem, we need to extend the route object creation rules so that it would be possible to create a route object that takes its authorisation from a collection of route and/or inetnum objects that are more specific than the route object to be created. As the situation is quite rare, the 'extended' behaviour can be activated by using the keyword 'EXTENDED-ROUTE-CREATION' in the subject line of the update message or with the syncupdates. The extended behaviour is not the default behaviour. The Algorithm: The proposed algorithm to authorise the route object creation is: Check if the keyword was used. If not, proceed with normal route creation rules as described in RFC2725 (http://www.ripe.net/ripencc/faq/database/qa4.html#5) Check if there is an exact match route object or an exact match inetnum object If there is one, then proceed with normal route creation rules even if the keyword was specified. Find the inetnums/routes that can be used for route creation: Get a list of all inetnums and route objects that are one level more specific than the route object to be created. (-r -Troute,inetnum -m <prefix>) From this list, eliminate the inetnums that have exact match or less specific route objects. (Note: During route object creation, the existing route objects take precedence over existing inetnum objects). Check if the resulting set of inetnums/routes cover the whole space of the route to be created. If not, authorisation fails, hence creation attempt fails. Collect the mntners to be used during the authorisation check. Follow these rules: For each object in the set, check if there are "mnt-routes:" attributes in the object. If there are, they will be used. If there are not, the mntners that are mentioned in "mnt-by:" attributes will be used. Check the authorisation: During the authorisation, the mntners in the same object will be ORed, while the mntners in separate objects will be ANDed.

The user wants to create the following route object: route: 12.0.0.0/23 origin: AS65534 mnt-by: MNT-ROUTE When the creation is attempted without the keyword 'EXTENDED-ROUTE-CREATION,' the whois software will try to get the IP space authentication from inetnums, as no related route object exists. The one level less specific inetnum is 12.0.0.0 - 12.255.255.255, which has the attribute "mnt-lower: RIPE-NCC-HM-MNT". As the user does not have access to the authorisation for RIPE-NCC-HM-MNT mntner, the creation attempt will fail.
