In this scenario, the packet has to visit the network layer twice.
The first visit to the network layer occurs at source S, where the packet is encapsulated with the necessary network layer information such as source and destination IP addresses.
Then, the packet is passed to the data link layer, where it is encapsulated with the necessary data link layer information such as source and destination MAC addresses.
The packet is then sent to the first intermediate router (R1). At R1, the packet is decapsulated at the data link layer to extract the network layer packet.
After processing at the network layer, the packet is again encapsulated at the network layer with the necessary routing information. It is then passed back down to the data link layer where it is encapsulated with the data link layer information.
The packet is then sent to the second intermediate router (R2). At R2, the packet is decapsulated at the data link layer to extract the network layer packet.
Finally, the packet arrives at the destination D. The packet is decapsulated at the data link layer to extract the network layer packet, and then processed at the network layer.
Therefore, the packet has to visit the network layer twice during the transmission from S to D.

Concept:
The Routers only contains 3 layer that's the reason sometimes they also called as 3-layer switch.
The Router is a physical or virtual internetworking device that is designed to receive, analyze, and forward data packets between computer networks. A router examines a destination IP address of a given data packet, and it uses the headers and forwarding tables to decide the best way to transfer the packets.
At Intermediate Router R the packet will not go beyond the network layer. Hence Network layer will only be visited once at both the routers.
But the Data link layer will be visited twice.
Hence Network layer will be visited 4 times and the Data link layer will be visited 6 times (1 + 2 (at R) + 2 (at R) + 1 = 6 )
At Intermediate Router R the packet will not go beyond the network layer. Hence Network layer will only be visited once at both the routers.
But the Data link layer will be visited twice.
Hence Network layer will be visited 4 times and the Data link layer will be visited 6 times (1 + 2 (at R) + 2 (at R) + 1 = 6 )
