Final answer:
Routers play a crucial role in routing packets between different subnets in an IPv6 network. Nodes, switches, and hubs have different roles in network communication.
Step-by-step explanation:
Routers play a crucial role in routing packets between different subnets in an IPv6 network. Routers are devices that connect multiple networks together and ensure the correct delivery of packets to their intended destinations. They use routing tables and protocols to determine the best path for packet transmission.
Nodes are devices that can send, receive, or forward network traffic. While nodes participate in the transmission of packets within a subnet, they do not typically perform routing functions for traffic between different subnets.
Switches are devices that enable communication between devices within the same subnet by directing packets based on MAC addresses. They do not perform routing functions between different subnets in an IPv6 network.
Hubs are devices that simply broadcast incoming packets to all connected devices in the same subnet. They do not have the intelligence to perform routing functions between different subnets.
