Subject: ipv6 global address remains while route item disappears after this interface is restared in 2.6.34.x
Date: Mon, 26 Aug 2013 10:28:03 +0800 [thread overview]
Message-ID: <521ABD33.7070905@gmail.com> (raw)
With two directly connected targets running kernel 2.6.34.x.
TargetA ------------------------- TargetB
3000::1/64 3000::2/64
TargetA
- bring the interface down by doing an "ifconfig eth1 down"
- bring the interface back up by doing an "ifconfig eth1 up"
TargetB
- ping6 3000::1
ping6 succeeds the first time
- after bringing the interface on TargetA down and then back up,
ping6 to the interface fails.
The root cause is:
IPv6 address 3000::1/64 remains while the ipv6 route on eth1 disappears.
Thus on TargetB, running "ping6 3000::1" can not succeed.
Compared with 3.4.x, ipv6 address and ipv6 route item are removed when
an interface is restarted in the.
Best Regards!
