Transport layer and Network layer.
Physical Data Link
Physical, Data link and Network layers make the Network Support layers.
Network Layer
identifies the network layer protocol makes the connection with the upper layers insulates network layer protocols from changes in physical equipment
insulates network layer protocols from changes in physical equipment makes the connection with the upper layers identifies the source and destination identifies the network layer protocol

Router works in Network Layer of OSI model
The Network Interface layer
seven
The INTERNET LAYER of OSI model exists for "routing" and providing a single network interface to the upper layers.
In computing, the Open Systems Interconnection model partitions a communication system into seven layers. They are the physical layer, the data link layer, the network layer, the transport layer, the session layer, the presentation layer, and the application layer.
