Hello
Because I did not send , and then retransmitted.
I am using the CentOS5.7.
In a state where the link down, I did a ping to the IPv4 and IPv6.
IPv4 succeeds in ping. but, IPv6 is ping fails.
Once confirmed by ifconfig, it did not have a Link-Local Address.
At link down, Is the Link-Local Address not set?
Leave the link down, Is there a way to avoid this?
# ethtool eth1
Settings for eth1:
?
Link detected: no
# ifconfig eth1
eth1 Link encap:Ethernet HWaddr 08:00:27:83:74:54
