When interface becomes down, ipv6 direct routes are not deleted

[Jiusheng Liu]

When I make the interface down by ifconfig, all the direct routes are
not deleted. And the addresses state are not changed. And I can even
ping those address in this interface.
Is this correct, or a bug? I test it in vmware virtual machine.

This is my first post to this mailing list, and I don't know if it is
the right place.
Any ideas are appreciated, thank you in advance.
