When using 'ip monitor all', prefix banner spamming of the object type occurs. On squeeze this does not happen (the object type is only printed once), so I presume the bug was introduced in a more recent version that made it into wheezy. difference between adding 'all' onto 'ip monitor' is that prefix banner printing is enabled. Here is a sample of the output I see on my wheezy install. Notice that several lines have "[ROUTE]" appended many times to the beginning.

Those [ROUTE] header are from entries from IPv6 cache which are being ignored by the filter.
