It can be made to sort of work for limited cases, but there’s no standardized way to make end-to-end connectivity work between all networks using the various bits of protocol and practice that we have at present.

I would define it as:
"Permission-less extensions of the network with new links (and by implications new routers) are not supported."

NPT66/NAT66 is the only alternative (talking network layer here).

If we have permission then:
 - normal managed network. Just add new router and run routing protocol. Manually managed addressing
 - HNCP (automated addressing and routing)
 - hierarchical DHCP PD (only works in single rooted DAG)
 - proxy ND (RFC recommending against)

Cheers,
Ole
