Bug Description
/etc/network/
$ ip -4 addr show dev eth0
2: eth0: <BROADCAST,
inet 10.1.1.51/24 brd 10.1.1.255 scope global eth0
inet 10.2.1.51/24 brd 10.2.1.255 scope global eth0
$ ip -6 addr show dev eth0
2: eth0: <BROADCAST,
inet6 xxxx:yyyy:
valid_lft forever preferred_lft forever
inet6 xxxx:yyyy:
valid_lft forever preferred_lft forever
inet6 fe80::aaaa:
valid_lft forever preferred_lft forever
(Global addresses and MAC address anonymized)
Both are configured within "manual" entries in /etc/network/
When I turn down eth0 and bring it up again, the result is:
$ ip -4 addr show dev eth0
2: eth0: <BROADCAST,
inet 10.1.1.51/24 brd 10.1.1.255 scope global eth0
inet 10.2.1.51/24 brd 10.2.1.255 scope global eth0
$ ip -6 addr show dev eth0
2: eth0: <BROADCAST,
inet6 fe80::aaaa:
valid_lft forever preferred_lft forever
That is, the global IPv6 addresses are lost.
