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.
