In the process of conducting the analysis, threats were identified that are not specific to Mobile IP but that are amplified by the nature of mobility. These threats are likely to be more or less of an issue within any Public Multi-Access network, regardless of whether mobility is involved. This document discusses threats associated with Public Multi-Access links in IPv6. The document covers non- Mobile IP specific threats uncovered by the Mobile IPv6 study, threats raised in the IPv6 Neighbor Discovery and Stateless Address Autoconfiguration RFCs that have yet to be adequately addressed, and new threats that have not previously been identified.

Problem statement for transit/exchange only IPv6 address space
by Janos Mohacsi 14 Nov '01

14 Nov '01

Dear All, Sorry for cross posting this message to more than one IPv6 related mailing list, but I think IPv6 community should prepare with some position to the transit/exchange only providers. I have seen the excellent presentation from Mirjam Kï¿½hne from RIPE-39 about IPv6 exchange proviers, but then I have not seen any discussion. My goal with this problem statement to increase the debate and hopefully reach some consensus about the problem. The problem statement is rather long.... Sorry about that. Kind Regards, Janos Mohacsi Problem statement for transit/exchange only IPv6 address space: The current Proposed TLA and NLA Assignment Rules (RFC 2450) and IPv6 Aggregatable Global Unicast Address Format (RFC 2374) is not particularly supporting addressing long haul transit providers or exchange providers. As RFC2374 states: "While this address format is designed to support exchange-based aggregation (in addition to current provider-based aggregation) it is not dependent on exchanges for it's overall route aggregation properties. It will provide efficient route aggregation with only provider-based aggregation." What is the current proposed solution to obtain IPv6 addresses for long-haul IPv6 transit providers or IPv6 exchange providers? To better understand the case I try to explain the problem more thoroughly. Let suppose the following situation: There is a long-haul ipv6 transit provider call it X. X is providing IPv6 transit or exchange service for ISPs Y1, Y2,....Yn. But X provide only IPv6 address assignment service for few customers of Yi, let say only for 4-5 customers, for one of the following reasons: 1. Most Y1,Y2, ... Yn has already production IPv6 subTLA 2. X company profile does not contain running local IP registry. 3. other reason X operates its offices in the area of Yi. For office purpose X can obtain IPv6 address from Yi. For IPv6 transit provision X needs an IPv6 address, but probably not /35 addresses, but /44 is enough, even if the transit network is quite extensive and geographically large. Scenario 1: X request address for its transit network from Yi, since his office is in the area of Yi. They get /44 from Yi (it must be difficult according to the current NLA allocation rules). X is implementing transit service and establishes private or public peering with ISP Z1, Z2, ... Zn and of course ISP Y1, Y2, ... Yn. To help the network management X implement and run some monitoring tools on the network near to monitored equipment. X can access its network, the involved network was network Yi. They are happy with the monitoring tools and X wants to share some results with Zk and Yj. Since the strict aggregation network addresses: of X-transit_network will be reacheable via Yi peering of Zk and Yj, not via peering of X-Zk and X-Yj that would be preferred. X can advertise more specific routes Zk and Yj, but this way X pollutes with non really aggregated entries the routing table of Zk and Yj. If they implement a really strict aggregation scheme then these more specific routes are discarded. How can X solve the problem? What happens if X wants to change provider from Yi to Yj? What happens if X has more than office one near to Yi and the other Yj? Which one should be used? Or some kind of multihoming should be used? Scenario 2: X request address (a subTLA) for its transit network from Regional IP Registry. X implementing IPv6 transit service and also network monitoring as before, but he does not allocate addresses just for few ISP Y. This somehow violates the current registration policy, since X does not fulfill all the 5.1 requirements of RFC 2450 and the corresponding RIR IPv6 allocation policy documents. There is no problem with accessing the services via the preferred peering since aggregation is done in X based on subTLA. Is this the current recommended solution? Scenario 3: X request address for office purpose only from Yi, and for the network they use site local address. The public and private BGP peering is quite problematical in this case, since some routers does not allow using local type IPv6 addresses in BGP peering. Providing the monitoring services can be also difficult, since monitoring tools cannot be reached outside of X transit network. This solution is not really acceptable. Or you have some other idea?

Title : Host-based IPv6 Multicast Addresses Allocation Author(s) : J. Park et al. Filename : draft-park-host-based-mcast-00.txt Pages : 6 Date : 13-Nov-01 This document specifies an extension to the multicast addressing architecture of the IPv6 protocol. The extension allows for sing interface-ID to allocate multicast addresses. When the link-local unicast address is configured at each interface of host, interface ID is uniquely determined. By delegating multicast addresses at the same time as interface ID, each host can identify their multicast addresses automatically at Layer 1 without needing to run an intra- or inter-domain allocation protocol in the serverless environments.
