Virtual Router: Software-Based Router

A software-based router that creates multiple virtual network interfaces and routes traffic between them, useful for testing and simulating complex networks.

What is Virtual Router?

A virtual router is a software application that performs the functions of a hardware-based router on a computer or server. Unlike a hardware router, a virtual router is not a physical device but rather runs as software on the operating system.

Some key capabilities and benefits of a virtual router include:

  • Enables routing functions to be performed in software without dedicated router hardware
  • Creates virtual network interfaces that can connect virtual machines or network segments
  • Routes traffic between virtual and physical network interfaces
  • Facilitates testing and simulation of complex network infrastructures and routing configurations
  • Provides network separation and traffic isolation for greater security
  • Offers flexible deployment options since it runs on commodity server hardware

Virtual routers provide extensive routing capabilities and control without needing dedicated hardware devices. They are commonly used for testing networking concepts, prototyping router configurations prior to deployment, replicating production environments for development or QA testing, and simulating complex network topologies and traffic patterns.
