Using GVRP
When GVRP GARP/Generic VLAN Registration Protocol. A network protocol for automatic configuration of VLAN information on switches. is enabled on a switch, the VID for any static VLAN Virtual Local Area Network. Separate logical broadcast domain created within a physical network. configured on the switch is advertised, using BPDUs (Bridge Protocol Data Units), out all ports regardless of whether a port is up or assigned to any particular VLAN Virtual Local Area Network. Separate logical broadcast domain created within a physical network.. A GVRP GARP/Generic VLAN Registration Protocol. A network protocol for automatic configuration of VLAN information on switches.-aware port on another device that receives the advertisements over a link can dynamically join the advertised VLAN Virtual Local Area Network. Separate logical broadcast domain created within a physical network..
A dynamic VLAN Virtual Local Area Network. Separate logical broadcast domain created within a physical network. (that is, a VLAN Virtual Local Area Network. Separate logical broadcast domain created within a physical network. learned through GVRP GARP/Generic VLAN Registration Protocol. A network protocol for automatic configuration of VLAN information on switches.) is tagged on the port on which it was learned. Also, a GVRP GARP/Generic VLAN Registration Protocol. A network protocol for automatic configuration of VLAN information on switches.-enabled port can forward an advertisement for a VLAN Virtual Local Area Network. Separate logical broadcast domain created within a physical network. it learned about from other ports on the same switch (internal source), but the forwarding port will not itself join that VLAN Virtual Local Area Network. Separate logical broadcast domain created within a physical network. until an advertisement for that VLAN Virtual Local Area Network. Separate logical broadcast domain created within a physical network. is received through a link from another device (external source) on that specific port.
Figure 1 Forwarding advertisements and dynamic joining
If a static VLAN Virtual Local Area Network. Separate logical broadcast domain created within a physical network. is configured on at least one switch port and that port has established a link with another device, then all other ports of that switch will send advertisements for that VLAN Virtual Local Area Network. Separate logical broadcast domain created within a physical network..
A port can learn of a dynamic VLAN Virtual Local Area Network. Separate logical broadcast domain created within a physical network. through devices that are not aware of GVRP GARP/Generic VLAN Registration Protocol. A network protocol for automatic configuration of VLAN information on switches.. VLANs must be disabled in GVRP GARP/Generic VLAN Registration Protocol. A network protocol for automatic configuration of VLAN information on switches.-unaware devices to allow tagged packets to pass through.
