File Content: changes.ipv6 v1.6 2nd Sep 2003, Pekka Savola <pekkas@netcore.fi> IPv6 CHANGES ============ This mentions the most important changes (visible to the administrator) in IPv6 initscripts. RHL9 -> CURRENT --------------- - no major functional changes, only bugfixes and cleanups RHL80 -> RHL9 ------------- - 6to4 device MTU is calculated explicitly, IPV6TO4_MTU support added - add route6-<device> static route support - secondary IPv6 addresses are configurable on tunnel interfaces too RHL73 -> RHL80 -------------- - no major functional changes RHL72 -> RHL73 -------------- - 6to4 device changed from sit0 to tun6to4 - 6to4 assumes the anycast (closest) 6to4 server is used (192.88.99.1) unless specified with IPV6TO4_RELAY. - 6to4 does not support automatic tunneling *at all* anymore; use IPV6_AUTOTUNNEL if you want to use it. - All support from NBMA tunnels as well as 6to4 using sit0 was removed - IPV6TO4_CONTROL_RADVD and IPV6TO4_RADVD_PIDFILE was changed to IPV6_*, respectively. - IPV6_DEFAULTGW and IPV6_DEFAULTDEV support was introduced; /etc/sysconfig/static-routes-ipv6 must not be used for them anymore. Rough guide to migration: - Rename IPV6TO4_CONTROL_RADVD to IPV6_CONTROL_RADVD if exists - Rename IPV6TO4_RADVD_PIDFILE to IPV6_RADVD_PIDFILE if exists - Remove "default" route from /etc/sysconfig/static-routes-ipv6 and replace it with something like IPV6_DEFAULTDEV=tun6to4 in /etc/sysconfig/network - If you need autotunneling, use IPV6_AUTOTUNNEL in /etc/sysconfig/network RHL71 -> RHL72 -------------- - 6to4 tunneling support was added using device sit0 - Tunneling method was changed from NBMA (now obsolete) to dedicated - Automatic tunneling configured was moved from ifcfg-sit0 to IPV6_AUTOTUNNEL at /etc/sysconfig/network Some more information --------------------- http://www.bieringer.de/linux/IPv6/IPv6-HOWTO/scripts/current/ ,in particular: http://www.bieringer.de/linux/IPv6/IPv6-HOWTO/scripts/current/index.html#migration Submit
