Chapter 8 GVRP Protocol Overview Typical 802.1q VLAN implementation involves network administrators manually configuring each Layer 2 switch that participates in a given VLAN. GARP VLAN registration protocol (GVRP), also defined by the IEEE 802.1q specification, is a Layer 2 network protocol that provides for the automatic VLAN configuration of switches. GVRP compliant switches use GARP to register and de-register attribute values, such as VLAN Ids, with each other. GVRP exchanges network VLAN information to allow switches to dynamically forward frames for one or more VLANs. Consequently, GVRP will spread this information and configure the needed VLAN(s) on any additional switches in the network. Information propagates via the exchange of GVRP protocol data units (PDUs). The purpose of GVRP is to simplify (but not eliminate) static configuration. The idea is to configure switches at the edge and have the information dynamically propagate into the core. As such, the edge ports must still be statically configured with VLAN membership information, and they do not run GVRP. It is this information that is propagated to create dynamic VLAN membership in the core of the network. • GVRP propagates VLAN membership throughout a network. GVRP allows end stations and switches to issue and revoke declarations relating to VLAN membership. • VLAN registration is made in the context of the port that receives the GARP PDU and is propagated tothe other active ports. • GVRP is disabled by default; you must enable GVRP for the switch and then for individual ports. • Dynamic VLANs are aged out after the LeaveAll Timer expires three times without receipt of a join message. Configuring GVRP GVRP configuration is per interface on a switch-by-switch basis. Globally, enable the GVRP protocol on each switch to facilitate GVRP communications. Basic GVRP configuration is a 2-step process: 1. Enable GVRP globally. See page 172. 2. Enable GVRP on an interface. See page 173 FTOS Configuration Guide, version <strong>7.6.1.0</strong> 171
