The IESG has approved the following document: - 'Analysis of Failure Cases in IPv6 Roaming Scenarios' (draft-ietf-v6ops-ipv6-roaming-analysis-07.txt) as Informational RFC This document is the product of the IPv6 Operations Working Group. The IESG contact persons are Joel Jaeggli and Benoit Claise. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-v6ops-ipv6-roaming-analysis/ Technical Summary This document identifies a set of failure cases that may be encountered by IPv6-enabled mobile customers in roaming scenarios. The analysis reveals that the failure causes include improper configurations, incomplete functionality support in equipment, and inconsistent IPv6 deployment strategies between the home and the visited networks. Working Group Summary China Mobile has been pretty openly discussing what they call "IPv6 Bearer Network Trials" starting at IETF 81. As one might imagine, they had various problems with routing (OSPF issues due to variable MTU, for example) and other operational aspects. They started discussing their issues in roaming at IETF 87, and other operators experimenting with the technology chimed in. This was accepted as a working group draft and discussed at IETF 89, and is now being filed. There has been active discussion on technical points, but little real dispute. Document Quality This is operational experience, and the author list reflects the set of companies reporting experience with it - Deutsche Telekom AG, Rogers, China Mobile, and Orange. Given the range of comments made, the document appears to cover the bases. Note that while the document specifically addresses 3GPP networks, it also comments on 2G and 4G, and by extension LTE.
