What is a VPN instance also known as?

A VPN instance is known as a VPN routing and forwarding table because it integrates both the routing information and the forwarding logic necessary for VPN operations. This table facilitates the separation of VPN traffic from different virtual networks, allowing for customized routing and forwarding of data packets based on the specific requirements of each VPN.

The "routing" aspect refers to how the network determines the best path for the data, while the "forwarding" aspect handles the actual transfer of packets to their destinations. This combined approach is crucial in a multi-tenant environment where multiple VPNs coexist, ensuring that each user or segment receives only the data intended for them.

This distinction enables the creation of secure, isolated pathways for data between users or sites, reinforcing the importance of both components in effective VPN management. The other terms listed do not encompass the comprehensive functionality associated with a VPN instance, as they either focus solely on routing or forwarding without indicating the holistic management of both aspects together.
