Add new package for configuring 6rd tunnels.
This patch adds support for manually configuring 6rd tunnels. It depends on
the netifd patches I sent earlier, which add 6rd support.
A basic interface configuration looks like:
config interface 'wan6'
option proto '6rd'
option peeraddr '192.0.2.1'
option ip6prefix '2123::'
option ip6prefixlen '16'
option ip4prefixlen '0'
Where ip4prefixlen is optional and actually defaults to 0, which would use all
bits of the IPv4 in the calculated IPv6 subnet.
I believe it should be possible to configure a regular 6to4 tunnel using this,
and that we may want to merge the two eventually, but there are some larger
differences between the two at the moment:
- 6rd addresses can be more difficult to calculate. My ISP, for example, has
a setup with a v6 mask of 43 bits, and a v4 mask of 19.
- 6to4 has support for configuring radvd. This is something we want, of
course, but it seems best to deal with this in a separate patch.
Just creating a new package looked like the quickest way to get this in.
This work is based on the 6in4 package, and work by Stijn Tintel.

Add new package for configuring 6rd tunnels.
This patch adds support for manually configuring 6rd tunnels. It depends on
the netifd patches I sent earlier, which add 6rd support.
A basic interface configuration looks like:
config interface 'wan6'
option proto '6rd'
option peeraddr '192.0.2.1'
option ip6prefix '2123::'
option ip6prefixlen '16'
option ip4prefixlen '0'
Where ip4prefixlen is optional and actually defaults to 0, which would use all
bits of the IPv4 in the calculated IPv6 subnet.
I believe it should be possible to configure a regular 6to4 tunnel using this,
and that we may want to merge the two eventually, but there are some larger
differences between the two at the moment:
- 6rd addresses can be more difficult to calculate. My ISP, for example, has
a setup with a v6 mask of 43 bits, and a v4 mask of 19.
- 6to4 has support for configuring radvd. This is something we want, of
course, but it seems best to deal with this in a separate patch.
Just creating a new package looked like the quickest way to get this in.
This work is based on the 6in4 package, and work by Stijn Tintel.
