Speaking of experience there is a difference potentially
between rfc1918/bogus/unallocated filters on an interface
that likely do reference a prefix list (no le/ge on
Junipers) - and a policy that handles BGP announcements.

It surely can happen (and did happen) that the BGP
announcements itself made it just fine while the filters on
the customer/ peer links where not at all updated yet (if
they filter BGP announcements for unallocated at all, etc).

Much less people filter BGP that hard, if at all, for
unallocated/ bogus, but rather keep the firewall policies
clean.
