Dear All,
I have problem setting up proper behaviour on bond0 interface.
I use Debian GNU/Linux 4.0 with kernel 2.6.21-2-686.
The link local address of the bond interface remains tenative. Suspecting,
that DAD fails on bond0 interface:
ip -f inet6 addr
1: lo: <LOOPBACK,UP,10000> mtu 16436
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth-right: <BROADCAST,MULTICAST,SLAVE,UP,10000> mtu 1500 qlen 100
inet6 fe80::214:22ff:fe13:ed7a/64 scope link
valid_lft forever preferred_lft forever
3: eth-left: <BROADCAST,MULTICAST,SLAVE,UP,10000> mtu 1500 qlen 1000
inet6 fe80::214:22ff:fe13:ed7a/64 scope link
valid_lft forever preferred_lft forever
4: bond0: <BROADCAST,MULTICAST,MASTER,UP,10000> mtu 1500
inet6 2001:db8:0:1:214:22ff:fe13:ed7a/64 scope global dynamic
valid_lft 2591839sec preferred_lft 604639sec
inet6 2001:db8:0:1::4/64 scope global
valid_lft forever preferred_lft forever
inet6 2001:db8:0:1::3/64 scope global
valid_lft forever preferred_lft forever
inet6 2001:db8:0:1::2/64 scope global
valid_lft forever preferred_lft forever
inet6 fe80::214:22ff:fe13:ed7a/64 scope link tentative
valid_lft forever preferred_lft forever
^^^^^^^^^
As you can see. I can set up global addresses as many as I want, but the
tantative status of link local address is worries me.
Are there any idea to resolve this issue?
Setting net.ipv6.conf.eth-left.autoconf = 0 and
net.ipv6.conf.eth-right.autoconf = 0 would resolve the issue?
