Re: Bonding and Neighbour Discovery on IPv6-only devices

Hello,

I suspect that there are some problems while switching slaves manually on 
IPv6-only bonds. I have tested that this does not work on 2.6.18 kernel 
(RHEL5). I looked at recent sources (2.6.26) and even though there were 
multiple changes in bonding code, I still don't see how this could work.

Testing setup
-------------

Two ethernets enslaved (eth2 and eh3), active-backup bond has IPv6-only 
address (no IPv4)

Everything works fine, but if we switch the slave doing

# ifenslave -c bond0 eth3

the incoming ping6 to this host stops for up to several minutes (waiting until 
the switch updates its caches).

We _just_ put in an IPv6 fix, FWIW...
