Package: ifupdown Version: 0.6.7 Severity: wishlist Tags: patch, ipv6 Hi aj!
Attached are the scripts setup-6to4 and clean-6to4 which are (prototype)
implementations of 6to4 support for ifupdown to put into if-{up,down}.d
respectivly. In the spirit of ipv6' autoconfiguration, I tried to keep
the needed configuration minimally.
Here is the documentation for the new configuration options the
implement:
use6to4 _yes|no_
If set to yes, use the outgoing source ip of this interface as
local endpoint fo a 6to4 tunnel. The address' basic format is
2002:<<ipv4>>::/16
6to4subnet _ipv6 address fragment_
This can be used to configure a subnet of the local 6to4 address
space on another interface; e.g. on a router. The fragment is
the local subnet, four hexadecimal digits, which is inserted
into the 6to4 addresses: 2002:<<ipv4>>:<<subnet>>::/64
6to4base_iface _interface name_
When configuring a 6to4 subnet, the 6to4 prefix is determined by
looking at this interfaces. Keep the base_iface in front of this
iface in "auto" directives to ensure proper configuration
sequencing.
Using the 6to4base_iface, one can keep the ipv4 address dynamic. In the
case of only one 6to4 tunnel, the base_iface could be inferred.
There is a obvious dependency between the main 6to4 interface and all
interfaces with an attached subnet.
The scripts use iproute to access networking information.
See
http://www.tldp.org/HOWTO/Linux+IPv6-HOWTO/configuring-ipv6to4-tunnels.html
for a simple 6to4 HOWTO.
