Public bug reported:
Binary package hint: netscript-2.4
Hello,
using static configured ipv4 and ipv6 in /etc/networking/interfaces with
ubuntu 10.04LTS 64 bits
like:
iface bck-int--eth1 inet static
address 119.72.176.36
netmask 255.255.255.240
ip-proxy-arp 0
ip-rp-filter 0
iface bck-int--eth1 inet6 static
address 2C00:1388:FFFF::3
netmask 124
ip-proxy-arp 0
ip-rp-filter 0
which works fine after a reboot, but when executing a manual "ifconfig
bck-int--eth1 down" and up afterwards the ipv6 address gets lost.
hereby the output of a scenario, where you can see the steps. and what
goes wrong. In the end i need a "ifconfig down" (again) folowed with
ifup "bck-int--eth1" to get my ipv6 address back
