Link Local Addresses - RFC 3330
by Diego Gosmar 23 Jul '03

23 Jul '03

Dear sirs, I'm the tech-c contact for the it.atlanet LIR. We have planned to use pubblic IP address in order to number the point-to-point links of our customers (i.e. leased line or xDSL customers). We think that public addresses is better because it eliminates the isseus related with overlapping of private addresses that some customers could use on their LANs attached to the CPEs (the Customer Premises Equipments linked to our network via point-to-point links). Those public addresses should be unique just on each fixed access router of our backbone network. So they can be re-used in different PoPs. Of course each customer link will need 4 or 2 (if we use the RFC3021) IP addresses. Since I've noticed that the address space 169.254.0.0/16 is reserved by the IETF (RFC 3330) for the "Link Local" purpose, I was wondering which is the exactly purpose of such addresses and if could be feasible to use them to number our customer links. Anybody of you have ever used or seen the above mentioned address space being used ? What do you think if we use the 169.254.0.0/16 address space for our customer point-to-point links ? Thanks in advance for your help !

EOF, Amsterdam, September - Call for Presentations
by Daniel Karrenberg 10 Jul '03

10 Jul '03

[apologies for duplicates, hint: they have the same message-id] Hi Network Operations Folk, the holiday period is starting! A good time to consider preparing a presentation at the European Operators Forum (EOF) to be held during the 46th RIPE meeting in Amsterdam on September 1st and 2nd. We would like to have as many practical, hands-on presentations as possible this time. Remember: They do not have to be long. We prefer an stand-up interesting 10 minute presentation over a well prepared 90 minutes explanation of something not so interesting to operators. Find some information about presenting below and think about all those experiences this year that might be interesting to other operators. For the EOF "Coordination Group". Daniel Karrenberg -------------------------------------------------------------------------- The EOF The European Operators Forum (EOF) exists for the exchange of Internet operations experience. It has evolved from the "information exchange" part of the early RIPE meetings to provide an open forum outside of the work programme of the working groups and the RIPE plenary. The EOF aims to attract presentations relevant to network operators, practical "hands-on" reports, outlines of future developments and small tutorials. Product marketing presentations are not appropriate, user experience reports are. The EOF programme is assembled by an informal coordination group that is always looking for new people who are able to help by attracting interesting presentations and supporting presenters. Contact: Daniel Karrenberg <daniel.karrenberg(a)ripe.net> Presenting at the EOF The EOF wants to attract practical hands-on experience reports. We aim to make turning interesting experience into a presentation as easy as possible. Consider the following: - presentations do not have to be long Something interesting can be said in as little as 10 minutes. This limits the time spent to prepare material and often is a good way to start for first-timers. - support is available We will do our best to support you in preparing your presentation. If you want, we can help structuring your material, help to polish language and arrange for a test-run of your presentation. We can also try to arrange for someone from the same country or region to support you if that is helpful. We can also help you find someone else to present your material in case you cannot make it to the meeting. In short: If you have something intersting to say, we will help you do it! Contact Daniel Karrenberg <daniel.karrenberg(a)ripe.net> for more information. - no product marketing presentations The EOF is *not* an appropriate forum for product marketing presentations. User experience reports which are presented by users are definitely relevant. In-depth technical presentations or tutorials are also possible. We expect to finalise the program in early August. We will get back to you then with scheduling details. In the meantime please provide the information below. We place special emphasis on the abstract which should contain references to related material already available if possible. Please send this to eof-coord at-sign ripe.net. - Author(s) - Speaker - (Working) Title - Abstract - Draft Presentation (if available) - Relation to other known work and/or presentations if known - Time Requested It would be helpful if the abstract was written such that potential attenders will learn what to expect from the presentation, i.e. "The presentation will describe our experiences with the Red Packet Washer (http://www.netdet.net/RPW/) We have been using the device for half a year now. It helps us deliver more hygienic datagrams to our customers and peers. We will discuss problems with packet discolouring as well as increased throughput to our upstreams due to decreased clogging by dirty micrograms. We will compare performance with the hand-scrubbing of packets which we used previously. Currently we are optimising device management and getting bugs resolved. We will strive to include the latest experiences in our report." is much better than "The presentation will describe the Red Packet Washer made by Network Detergents." More information about the meeting can be found at http://www.ripe.net/ripe/meetings/ripe-46/index.html Should you have questions, please do not hesitate to contact me by e-mail at any time. During July and August my response time may be slightly longer than usual due to the holiday period. Thanks Daniel
