A virtual node is an interface to End user / Portal for Redirecting to SAP application.

Virtual node is identified by Virtual IP and the hostname.

Virtual IP is a free unused IP in the Domain / network.

Virtual Hostname should be entered in the DNS as it is being accessed by the end user.

Virtual URL is the URL which would be redirecting to the SAP application.
