That's why I hope Juniper will fix their implementation not to reset
the session and to stop using an old key.  Once the key is changed, all
new packets (including new packets for old sessions) should use the new
key, not the old key.

You think the bug is on Cisco's side, I think the bug is on Juniper's
side.  Hence interoperability.
