ipv6 global address remains while route item disappears after this interface is restared in 2.6.34.x

2013-08-25 Thread zhuyj

With two directly connected targets running kernel 2.6.34.x.

TargetA - TargetB
3000::1/643000::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!
