[routing-wg]More specific prefix announce
by dendy＠ulm.udsu.ru 02 Sep '05

02 Sep '05

Hello. Unfortunately, I'm not so experienced in the question to anwer that. Therefore I ask for help and will be thankful for any clarification. We have a /20 ASSIGNED PI address block and an AS. Is it allowed by RIPE policy to intentionally announce more specific prefix than one we have from our AS to upstream ASes? For example, announce our X.X.0.0/20 to upstream A and announce both X.X.0.0/20 and X.X.6.0/23 to B? -- Denis Tatarskikh [UdSU/MF] [UdSU/IC] mailto:dendy@udsu.ru

[routing-wg]RIPE Policy Development Process
by Paul Rendek 01 Sep '05

01 Sep '05

Dear Colleagues We are pleased to announce that Rob Blokzijl, RIPE Chair, has published a new RIPE Document, "Policy Development Process in RIPE", (ripe-350). This document formally describes the policy development process. The updated process is operational from today, 1 September 2005. A new RIPE web page describes all the active policy proposals and their status. Each proposal has a page showing its history, status and all supporting documentation. This page can be found at: http://www.ripe.net/ripe/policies/proposals/index.html A new mailing list <policy-announce(a)ripe.net> has been created for announcing policy proposals and tracking them through the policy development process. This is not a discussion list; discussions will continue to take place on relevant RIPE Working Group lists and at RIPE Meetings. You can subscribe to the policy-announce list at: http://www.ripe.net/mailman/listinfo/policy-announce List archives are available at: http://www.ripe.net/ripe/maillists/archives/policy-announce/ Kind regards Paul Rendek Head of Member Services and Communications RIPE NCC
