A network administrator is implementing OSPF on all of a company's network devices. Which of the following will MOST likely replace all the company's hubs?
- A layer 3 switch is a type of network switch that can perform routing functions in addition to the basic switching functions of a layer 2 switch. OSPF (Open Shortest Path First) is a routing protocol used for distributing routing information within a single autonomous system (AS) and improving the routing efficiency and reliability within a network.
The OSPF (Open Shortest Path First) protocol is one of a family of IP Routing protocols, and is an Interior Gateway Protocol (IGP) for the Internet, used to distribute IP routing information throughout a single Autonomous System (AS) in an IP network.
A. A Layer 3 switch
OSPF (Open Shortest Path First) is a dynamic routing protocol used in Internet Protocol (IP) networks. It requires a device that can understand and implement Layer 3 (network layer) operations.
Hubs are Layer 1 (physical layer) devices, and they simply broadcast all data to every device connected to them without any sort of routing intelligence. Switches, specifically Layer 3 switches, work at both the data link layer (Layer 2) and the network layer (Layer 3). Layer 3 switches can manage both the switching and routing operations, and they're capable of working with protocols such as OSPF.
It should be a layer 3 switch which also acts a router.
