1 IPv6 Release Notes This document discusses the most recent product information pertaining to IPv6. It also discusses how to install the new features in IPv6 on the HP-UX 11i v3 operating system. This document addresses the following topics: • • • • • • • • • • “Announcement” (page 6) “What Is New In the B.11.31.0907 Version of IPv6” (page 6) “Features in the B.11.31.0809 Version of IPv6” (page 7) “Feature in the B.11.31.
Announcement IPv6 is the next generation Internet Protocol. The IPv6 protocol is also referred to as "IPng" (IP next generation). It provides the infrastructure for the next wave of Internet devices, such as PDAs, mobile phones, and appliances. It also provides greater connectivity for existing devices, such as laptop computers. IPv6 was designed by the Internet Engineering Task Force (IETF) to improve upon the scalability, security, ease of configuration, and network management capabilities of IPv4.
Features in the B.11.31.0809 Version of IPv6 The B.11.31.
Support for RFC 3484 (Default Address Selection for Internet Protocol version 6 (IPv6)) A typical IPv6 host can be assigned multiple addresses with different characteristics, such as link local address, global address, temporary address, unique local address, special purpose addresses for IPv4-IPv6 transition. Additionally, if the host is dual-stack, it is also configured with IPv4 addresses. This leads to multiple possible source and destination address choices while initiating communication.
Support for IPv6 over VLAN The B.11.31.0809 version of IPv6 provides support for IPv6 over virtual LAN (VLAN). For more information on VLAN configuration, see the VLAN Administrator's Guide: http://www.docs.hp.com. Ability to Disable Autoconfiguration Based on Router Advertisements Starting with this release of IPv6, HP provides the ability to disable autoconfiguration based on the contents of the received router advertisements using the ip6_nd_autoconf tunable in the ndd command.
enable applications to specify the source filters to the underlying IGMPv3 and MLDv2 protocols. Feature in the B.11.31.0803 Version of IPv6 The B.11.31.0803 version of the IPv6Upgrade bundle supported the privacy extension to IPv6 auto-configuration feature, which is based on RFC 4941 (Privacy Extensions for Stateless Address Autoconfiguration in IPv6).
NOTE: The IPv6Upgrade bundle sets this tunable to 2 to enable the RFC 3810 functionality. ip6_addr_sel_enable Enables or disables RFC 3484. This tunable specifies the default address selection for IPv6. The default value of this tunable is 0. NOTE: The IPv6Upgrade bundle sets this tunable to 1 to enable the RFC 3484 functionality. ip6_icmp6_extended_errors Specifies whether to report additional ICMPv6 error messages as defined in RFC 4443. The default value of this tunable is 0.
ip6_nd_autoconf Controls IPv6 auto-configuration from the router advertisement. The default value of this tunable is 1. ip6_mld_compat_disable Controls compatibility with the old version of MLD. The default value of this tunable is 0. ip6_mld_rv Specifies the MLD robustness variable. The default value of this tunable is 2. ip6_mld_maxsrc Specifies the maximum source addresses in the MLDv2 filter. The default value of this tunable is 128.
Changed and Unsupported Features Following are the changed and unsupported features in this release of IPv6: • • The usage of IPv6 site-local unicast addresses with prefix fec0::/10 is deprecated. Unique local IPv6 unicast addresses (RFC 4193) can be used for local communications. The IPv4-compatible IPv6 address, (for example, ::a.b.c.d) is deprecated. Installing the IPv6Upgrade Bundle This section describes how to install the IPv6Upgrade bundle.
10. Select the IPv6Upgrade bundle depot under Download Software. 11. Save the IPv6Upgrade bundle depot in a local directory, for example, /tmp. 12. To verify that the IPv6Upgrade bundle depot is downloaded properly in the local directory, enter the following HP-UX MD5 Secure Checksum command at the HP-UX prompt: # md5sum The result of this command must match the fingerprint provided in the Electronic Delivery Receipt. If the result does not match, download the IPv6Upgrade bundle depot again.
