+Subject: ip6: ignore cached/cloned route notifications from the kernel (lp:1038541) (bgo #671767)
+
+The kernel periodically adds routes for specific operations, including
+when pinging any host.  These are temporary routes and aren't part of
+the interface's permanent routing configuration, so we should ignore
+them.
