Filtering PIM joins on an IRB interface?

How to correctly filter PIM joins in policy-options/policy-statement on an IRB interface.

In order to reject PIM for a local RP between group 249.255.0.0/16 and source 10.15.29.224/27, you can use a specific filter in policy-options/policy-statement called ‘pim-join-filter’ trying to reject this specific join:

An IRB interface the PIM filter being used to block the source address will not work properly.

A firewall filter needs to be used to block the specific source address, instead of a policy. If the filter shown above is used on a regular interface (non-IRB) then it will work as expected.
