[routing-wg]intra-system private addresses
by Allwyn Carvalho 21 Jun '06

21 Jun '06

I am a new member to this list, so apologies if this question has come up before. I was wondering if there are any IPv4 addresses reserved for communication within one logical system. For example, a system (router for example) with multiple slot cards may require one slot card to communicate via IP directly with another slot card, and even route traffic between the cards. Traffic to these destinations will always originate from within the logical system and will never leave the logical system. The system itself could be modular, and be built from several components. Is there any ip-address range reserved for this? I took a look at RFC 3330, but it's not obvious what could be used. Using the addresses reserved for private networks (10.0.0.0/8, 172.16.0.0/16, and 192.168.0.0/16 etc.) is not attractive because there could be a large number of components and we do not want to preclude use of these addresses in the rest intranet. Thanks in advance. Allwyn.

[routing-wg]Re: Possible IAB workshop on routing and addressing participants?
by David Meyer 19 Jun '06

19 Jun '06

[Sorry about the wide distribution/duplicates. Just trying to reach as many of the folks who may be interested as possible --dmm] Folks, The IAB is considering holding a routing and addressing workshop, perhaps in the fall 2006 time frame (see the draft invite below). We're in the process of collecting potential participants, so please pass along any the names of folks that that you think would be productive participants. Thanks, --dmm (for the IAB) ---- Greetings, The IAB is sponsoring a workshop on "Scalable Routing and Addressing Architectures for the Internet" in order to foster interchange between the operator, standards, vendor, and research communities on this important topic. You are being invited to participate in this effort. This workshop effort will consist of mailing list discussions in advance of, and after a face to face meeting. The technical goals of this effort are outlined below. We believe these are the critical elements to fostering a constructive discussion of important routing and addressing technical work going forward and are soliciting workshop participation to work towards those goals. Should you decide to join us in this workshop, you will be expected to attend the face to face meeting [0], contribute to (and possibly present at) that meeting, as well as follow and participate in the mailing list discussions. The most important objective of the workshop is to foster and encourage innovative thinking in an area where there has been little fundamental change for the last twelve years. As such, the primary goals of the workshop include the following two items: (i). Produce a concise problem statement that will serve as the input to future work on this topic. This problem statement will include, among other things, a list of the problems with the current routing and addressing architecture. These include (but are not limited to): - The difficulty in changing provider due to PA/CIDR addressing schemes - The lack of effective multi-homing support - Limited capability to protect against either the spoofing of individual host IP addresses or entire IP address blocks - The limited ability to secure the routing system itself, and (ii). Produce a prioritized list of requirements, all of which must be met by a next generation routing and addressing architecture. A sample list might include (in no particular order): - Retaining the connectionless datagram model of IP routing - Allow users (small and large) to freely switch between providers without substantial service interruption - Include survival of higher-layer connections and associations when connectivity to individual providers changes - Allow both users and ISPs to influence path selection according to traffic management and classification requirements - Provide better support for mobility and nomadicity - Provide architected instrumentation facilities - Allow at least one-to-many multicast - Prevent source address spoofing - Provide a rational economic basis for deployment - Secure the routing infrastructure, including the authentication of updates and the unauthorized injection of information into the routing system - Define scalability requirements for a next generation routing system - Have architected transition mechanisms and be incrementally deployable (where possible) During the workshop, scribes will be assigned to summarize the discussion. Post-workshop, scribes will be expected to participate in finalizing the workshop report. All participants will be expected to review the draft workshop report before publication. The workshop is <date, <logistics. Please reply within the next week indicating your willingness to participate in this workshop. Please indicate whether (and to what extent) you'd be able to participate (we'd like an explicit 'no' if you will not be able to), and what you feel is your area of expertise. If you can not participate, please suggest potential alternatives or substitutes. [0] Attendees will also need to arrange and pay for their own travel and accommodations.
