Charter 6rd configuration

It’s good to know, that Internet Service Provider CHARTER is getting ready for IPv6. There is a trial program, and here is working Linux configuration:

#edit /etc/config/network
#/etc/init.d/network reload
config interface 'wan6'
        option proto '6rd'
        option peeraddr '68.114.165.1'
        option ip6prefix '2602:100::'
        option ip6prefixlen '32'
        option ip4prefixlen '0'

With this configuration it’s possible to browse websites like whatismyv6.com, ip6.me, ipv6-test.ch, test-ipv6.cl, speedtest6.cesnet.cz, and more, or to ping IPv6 addresses below.
