There are some standards based versions like GARP and GVRP, though Cisco has limited support for them, and, thus, isn't covered in the switching test. VTP uses layer-two trunk frames to transmit VLAN information to all participating switches, but only over trunk ports. It provides a central point of management for adding, removing, and renaming VLANs across a domain. A group of switches participating in VTP are all part of a management domain. A switch can belong to only a single VTP domain at a time. When a VLAN is added to the domain, VTP advertisements are sent sharing the addition. VTP supports several modes that changes a switch's relationship to the domain. Server mode is the default VTP mode. It allows a switch to create new…
