| 3 | IPv6 CHANGES |
---|
| 4 | ============ |
---|
| 5 | |
---|
| 6 | This mentions the most important changes (visible to the administrator) |
---|
| 7 | in IPv6 initscripts. |
---|
| 8 | |
---|
| 9 | RHL9 -> CURRENT |
---|
| 10 | --------------- |
---|
| 11 | |
---|
| 12 | - no major functional changes, only bugfixes and cleanups |
---|
| 13 | |
---|
| 14 | RHL80 -> RHL9 |
---|
| 15 | ------------- |
---|
| 16 | |
---|
| 17 | - 6to4 device MTU is calculated explicitly, IPV6TO4_MTU support added |
---|
| 18 | - add route6-<device> static route support |
---|
| 19 | - secondary IPv6 addresses are configurable on tunnel interfaces too |
---|
| 20 | |
---|
| 21 | RHL73 -> RHL80 |
---|
| 22 | -------------- |
---|
| 23 | |
---|
| 24 | - no major functional changes |
---|
| 25 | |
---|
| 26 | RHL72 -> RHL73 |
---|
| 27 | -------------- |
---|
| 28 | |
---|
| 29 | - 6to4 device changed from sit0 to tun6to4 |
---|
| 30 | - 6to4 assumes the anycast (closest) 6to4 server is used (192.88.99.1) |
---|
| 31 | unless specified with IPV6TO4_RELAY. |
---|
| 32 | - 6to4 does not support automatic tunneling *at all* anymore; use |
---|
| 33 | IPV6_AUTOTUNNEL if you want to use it. |
---|
| 34 | - All support from NBMA tunnels as well as 6to4 using sit0 was removed |
---|
| 35 | - IPV6TO4_CONTROL_RADVD and IPV6TO4_RADVD_PIDFILE was changed to |
---|
| 36 | IPV6_*, respectively. |
---|
| 37 | - IPV6_DEFAULTGW and IPV6_DEFAULTDEV support was introduced; |
---|
| 38 | /etc/sysconfig/static-routes-ipv6 must not be used for them anymore. |
---|
| 39 | |
---|
| 40 | Rough guide to migration: |
---|
| 41 | - Rename IPV6TO4_CONTROL_RADVD to IPV6_CONTROL_RADVD if exists |
---|
| 42 | - Rename IPV6TO4_RADVD_PIDFILE to IPV6_RADVD_PIDFILE if exists |
---|
| 43 | - Remove "default" route from /etc/sysconfig/static-routes-ipv6 and replace |
---|
| 44 | it with something like IPV6_DEFAULTDEV=tun6to4 in /etc/sysconfig/network |
---|
| 45 | - If you need autotunneling, use IPV6_AUTOTUNNEL in /etc/sysconfig/network |
---|
| 46 | |
---|
| 47 | RHL71 -> RHL72 |
---|
| 48 | -------------- |
---|
| 49 | |
---|
| 50 | - 6to4 tunneling support was added using device sit0 |
---|
| 51 | - Tunneling method was changed from NBMA (now obsolete) to dedicated |
---|
| 52 | - Automatic tunneling configured was moved from ifcfg-sit0 to |
---|
| 53 | IPV6_AUTOTUNNEL at /etc/sysconfig/network |
