[routing-wg]On Vince's talk
by Joao Damas 05 Oct '06

05 Oct '06

Sorry I had to cut the line at the microphone. Hans Peter Holen would you care to send your comment to the list? In addition, while watching Vince's presentation, and seeing how the little IPv6 would contribute to the total sum of routes one would be seeing announced to the Internet (internal routes are each ISP's problem in this context, to some extent) I was wondering what would actually happen towards the time around which *new* IPv4 addresses would become scarce and people are forced to change the way IPv4 is used (eg, by splitting current allocations and trading those smaller chunks). Then the question might become, what would the mess look like if there is no IPv6 deployment? and does the picture Vince hinted at become any worse in the absence of IPv6 deployment, even with the less than perfect routing solutions currently available?

Dear Community, the logistical infrastructure for the Data Protection Task Force has been set up by the NCC. It is available at http://www.ripe.net/ripe/tf/index.html We are trying to get together a reasonably diverse mix of people for this task force, representing the various roles, activities and types of interest. The TF will be presented and discussed on Fr. morning in the DB-WG session where we will try to collect the initial population. If you can't make it to the DB-WG meeting, please indicate your interest by personal mail to Jochem de Ruig and myself. Please read up on the TF's mandate, the goals and logistics, and consider stepping forward to *actively* contribute! Thank you. See you Friday morning, Wilfried.

[routing-wg]Multihoming in IPv6 using PA space
by Iljitsch van Beijnum 28 Sep '06

28 Sep '06

[Going out to routing-wg and ipv6-wg, trim as needed in follow-ups] Before the last IETF meeting there was some discussion about the difficulties in multihoming using a prefix out of PA space from an ISP in IPv6. Because many ISPs filter at /32 or /35 in IPv6, the /48s (or /56s) used for multihoming are often filtered out. After some discussion with people from the IETF v6ops wg, I've written the draft mentioned below, outlining the problem and proposing a BGP community to tag the prefixes used for this so they can be un-filtered as needed. Feedback from people involved with and/or an interest in IPv6 routing is highly appreciated. I'd be happy to discuss the draft in either the routing or IPv6 wgs, or talk about it briefly at the end of my IPv6 routing tutorial on wednesday morning. And of course one-on-one in the hallway. The -01 with only minor changes should be up soon, or you can find it at http://www.muada.com/drafts/draft-van-beijnum-v6ops-pa-mhome- community-01.txt Begin forwarded message: > A New Internet-Draft is available from the on-line Internet-Drafts > directories. > Title : BGP Community for PA Multihoming > Author(s) : I. van Beijnum > Filename : draft-van-beijnum-v6ops-pa-mhome-community-00.txt > Pages : 8 > Date : 2006-9-11 > When an organization wants to connect to the internet using two or > more > Internet Service Providers (multihoming), this is usually done by > setting up BGP routing between the organization in question and > each of > its ISPs.
