1.2. Expectations of Link-Layer Type

In compliance with the layered architecture of IP, RPL does not rely on any particular features of a specific link-layer technology. RPL is designed to be able to operate over a variety of different link layers, including ones that are constrained, potentially lossy, or typically utilized in conjunction with highly constrained host or router devices, such as but not limited to, low-power wireless or PLC (Power Line Communication) technologies.

Implementers may find [RFC3819] a useful reference when designing a link-layer interface between RPL and a particular link-layer technology.
