If there are multiple LBR's, with different PIO's, the network still
needs a single CO. For example, a possible Smart Grid network would be
to have: An LBR in the meter with a PIO of the back haul to the utility
and a prefix assigned by the utility. A second LBR in a broadband
router with general access to the Internet and a prefix assigned by an
ISP. The LBRs would need to be configured to cooperate correctly so
there is only one set of context information in the network but each LBR
may be advertising a different PIO.
I am not sure in this case if both LBRs advertise both PIO's or each
advertises its own PIO. If both advertise both PIOs, the optimisation
is lost and the CO needs to be carried explicitly. If each just
advertises its own PIO, there is potential for confusion as two
different default COs may be derived.

We really can't mess with PIO, but how about this. We make a rule that is a single PIO is present in an RA, then it is assumed that this is CID=0 by default.
