Adding ND to bonding?

Adding ND to bonding?

[Roy Sigurd Karlsbakk]

Hi all

We're hoping one day we can move to an IPv6-only network (with some gatewaying to IPv4 land), and I wonder if it would be hard to add Neighbor Discovery Protocol to bonding as to allow for bonding on ipv6. I'm not much of a kernel coder, but for what I could see, it looks doable.

Anyone here that has looked into this?

Vennlige hilsener / Best regards

	I haven't tested it lately, but I'm reasonably sure that ND runs
over bonding.  Is there something specific you have in mind here?

Perhaps I was a bit unclear about this. What I mean, is that in the active-backup mode, the method of finding whether or not a link is active, is to send an ARP request to some machine, in my case, the gateway. This won't work with an IPv6-only configuration, since there's no ARP there, only ND. For active-backup mode to work in IPv6, there needs to be added an ND mode, replacing or supplementing ARP.
