SVI
In computer science, SVI stands for Switched Virtual Interface.
It is a technology used in networking to enable a single physical interface on a network switch to have multiple logical interfaces, each with its own unique IP address.
Switched Virtual Interfaces are primarily used in virtual local area networks (VLANs) where a switch can have multiple VLANs configured. Each VLAN can be associated with a unique IP subnet. By creating SVIs, the switch acts as a virtual router, allowing communication between different VLANs by routing the traffic between them.
SVIs are typically used in Layer 3 switches to provide routing capabilities within a network. They allow for the creation of virtual interfaces on the switch, which can be assigned IP addresses and used for inter-VLAN routing. This means that traffic between different VLANs can be routed at the switch level, eliminating the need for an external router.
By using SVIs, network administrators can simplify their network topology and reduce the dependency on external routers. It also provides better scalability and flexibility in managing VLANs and their associated IP subnets.
In summary, SVI (Switched Virtual Interface) is a technology that allows a switch to have multiple virtual interfaces, each with its own IP address, enabling routing between different VLANs within a network.
