Routing And Switching Questions
A virtual IP address (VIP) is a network address that is not associated with a specific physical device but rather with a virtual resource or service. It is used in network load balancing and high availability scenarios to provide a single entry point or endpoint for clients to access multiple servers or resources. The VIP is typically assigned to a load balancer or a cluster of servers, and it can be dynamically reassigned to different physical devices as needed. This allows for seamless failover and scalability, as clients can continue to access the service even if the underlying physical devices change.
