Eventually the two default proto kernel routes disappear from the output. My IPv6 connection still dropped at some point over night though. Again, simply running
sudo service networking stop && sudo service networking start got everything working again. Those two
fe80 routes reappeared as well, not surprising. Anyone any ideas?
aside: at no point has any IPv4 connectivity had issues.
The correct way to configure IPv6 in Debian’s
/etc/network/interfaces file is:
iface eth0 inet6 static address 2001:1af8:4100:a00e:4::1 netmask 64 gateway 2001:1af8:4100:a00e::1
You should not have any of those extra
up statements to configure your IPv6 address.
