Cisco IOS IPv6
Most of Cisco’s IOS based routers support a very broad range of IPv6 features and subprotocols with the right IOS version. This page compiles basic information on the various IPv6 capabilities of the IOS 12.2T and 12.3 and 12.4 release trains.
The information is mostly based on the exhaustive Cisco documentation and checked with the results of Defense Information Systems Agency/Joint Interoperability Test Command (JITC) compliance tests . Since IOS releases generally have the same feature set across different routers and product families the remarks here should apply to other Cisco systems running the same IOS versions as well.
Connectivity
Several updates regarding operational issues, including connectivity. After a short transition period, this site changed its IP connectivity and URL — it is now reachable at ipv6int.net; a HTTP redirect is configured for the old URL.
On a sidenote regarding IPv6 access — we're seeing a constant month-to-month ratio of about 8-11 percent of visitors accessing this site over IPv6. For comparison, at our sister site OpenPA.net about 1 percent of all accesses come over IPv6.
Operating systems IPv6 conformance — JITC
Several operating system pages have been updated with IPv6 protocol conformance/RFCs, including:
- Solaris 10
- Windows Vista SP1
- HP-UX 11i v3
- Linux 2.6 — the data from two distributions has been
used for this — there will probably be no single representative
Linux IPv6 compliance
The information is based on test and conformance documents from the Defense Information Systems Agency/Joint Interoperability Test Command (JITC) Approved Product List.
