RPL doesn't do this in protocol, but then, neither does ND.
I wouldn't extend RPL to do this, however, I'd send a DHCPv6 PD format
message. It can be a single exchange, and nobody said a single program
can't speak multiple protocols.
But, I question whether one always needs to get address space, vs
announce it. I don't know the answer: it really depends upon who your
second vehicle needs to talk to, and why it thinks that vehicle one (and
vehicle one's ISP) is willing to give it bandwidth.
If you don't want to speak RPL, then you need to pick the TBD
homenet-routing-protocol.
We don't need a third.
