I can't answer your question, but have one of my own - can you do IPv6
with this nowadays?  "backup interface" suppresses the "I have seen this
IP config elsewhere!" check, but they forgot to do this for IPv6 as well
(and I have lost the need to do backup interface, as we moved to
6500s and just do port-channels or "put both interface into the same
vlan, use SVI").
