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 |
