Configure ISATAP IPV6 tunnel under Fedora 9

 

Fedora 9 is changed to 2.6.25 kernel and 2.6.25 supports ipv6 tunnel access in ISATAP mode. So I simply configured my machine to support IPV6.

1: Ensure that kernel supports ipv6

2: edit/etc/sysconfig/network and add the following line.

Listen 6_defaultgw = your ipv6 gateway

3: edit/etc/sysconfig/network-scripts/ifcfg-sit1 with the following content

DEVICE = sit1

ONBOOT = yes

IPV6INIT = yes

IPV6TUNNELIPV4 = your isatap tunnel IP

IPV6TUNNELIPV4LOCAL = your local ipv4 ip

IPV6ADDR = your ipv6 address

4: ifup sit1

UPDATE: I have not tested whether the restart on F9 is valid, but it is not useful on centos 5.1. It seems that ifup-sit will not create the corresponding sit1 device, it is valid only after being manually created.
