Yes there can be situations like with multipoint NBMA where a
candidate rp or mapping agent advertisement comes in and needs to be
sent back out the same interface, but can't due to the OIL restrictions
(incoming and outgoing interface can't be the same). There are
workarounds for this like assigning default RPs for 224.0.1.39 and
224.0.1.40 and using NBMA mode, but BSR avoids this completely because
all the messages are sent on a hop by hop basis, unlike Auto-RP.
