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.
