In the previous note, I meant the BMR used as FMR, to be technical. But
here's another point from the same section:
The length of r MAY be zero, in which case the complete IPv4 address
or prefix is encoded in the EA bits. If only a part of the IPv4
address/prefix is encoded in the EA bits, the Rule IPv4 prefix is
provisioned to the CE by other means (e.g. a DHCPv6 option).
Question: does that second sentence also assume r = 0? If so, I think
you've moved beyond what makes sense to document as part of MAP-E. Given
that you have the MAP-E BMR mechanism, why wouldn't you use it?
