What is the main advantage of a virtual router over a physical router? Familiarity is invaluable, and there are many tutorials available online that will get you started. Virtual routing network functions are a type of virtualization (NFV).
Traditional hardware-based network appliances turn to software that can work on standard commercial off-the-shelf (COTS) hardware. Instead of having a proprietary hardware platform, it offers the benefit of reducing hardware costs and increasing hardware compatibility.

What Key Advantage Does a Virtual Router
A virtual router, also called a router, is a software function that mimics the capabilities of a hardware-based Layer 3 Internet Protocol (IP) routing system, which previously required a specific hardware device. The router is a general term for virtual routing used in the names of many brand name commercial devices.
What Is Virtual Routing And Forwarding?
Virtual Routing and Forwarding (VRF) is a feature of IP network routers that allows multiple routing tables to be in the same virtual router and work simultaneously. This feature improves the connection by enabling the distribution of network paths without the need to use multiple devices.
VRF enhances network security by automatically isolating traffic and eliminates the need for encryption and authentication. Internet service providers often use is to create different virtual private networks (VPNs) for users. VPN routing and forwarding is a term that describes how this is done.

A physical router is a router that allows clients to communicate with other networks or the Internet. It is also called a logic router because it routes IP packets based on addresses in router routing tables. Physical routers have a MAC address as well as an IP address.
Difference Between Virtual Routers And Physical Routers
Virtual routers are similar to traditional routers in that they act as an access point for communication between clients and other networks, as well as the Internet. However, the main difference between a virtual and a physical router is the state of the router. Virtual routers are usually stable, meaning they do not communicate with clients or other networks. It becomes operational only when the first or master router is down or unable to provide services. Virtual routers are also called backup routers because of this.
Rights and services are transferred from the master router to the backup router without interruption of service. VRRP is the protocol that ensures the smooth transfer of services from one router to another (virtual router redundancy protocol). RFC 2338 and RFC 5798 describe the protocol. Like a physical router, a virtual router has its VRID (Virtual Router Identifier) and a MAC address and IP address.
VRRP packets have the two most essential features of priority and validation type. Stress is determined by the value of the priority field, which ranges from 0 to 255, 255 is the master, and 0 is virtual. There are three basic modes of operation for the backup state, master state, and stylized state virtual routers. A physical router is a router that allows clients to communicate with other networks or the Internet.
It is also called a logic router because it routes IP packets based on addresses in router routing tables. Suppose the physical router is used as a backup instead of VRRP. In that case, the services will not be transferred directly from the master to the backup unless the routing table of the backup router is manually filled ۔ Physical routers have a MAC and an IP address. In their packets, they do not include the priority level field.
