Question

Accepted Answer

Routers and switches are network devices that operate at different layers of the OSI model. They have different functions and use different protocols and configuration commands.

Routers operate at the network layer (Layer 3) and are responsible for forwarding data packets between networks.
Switches operate at the data link layer (Layer 2) and are responsible for forwarding data frames within a network.
Routers use routing protocols such as OSPF, BGP, and RIP to determine the best path for packet forwarding.
Switches use MAC address tables to determine the destination of data frames within a network.
Common configuration commands for routers include setting up IP addresses, configuring routing protocols, and creating access control lists.
Common configuration commands for switches include setting up VLANs, configuring port security, and enabling spanning tree protocol.
Example: Router configuration command - 'interface GigabitEthernet0/0/0', Switch configuration command - 'vlan 10'
