VTP vs GVRP, the winner? Neither..

In a large network, keeping VLANs synchronized can be a challenge. Having automatic tools to ensure automatic and correct distribution of VLANs helps to reduce the chance of some of our human errors and typo's, and also just to make our lives easier

Two fairly well-known protocols that are capable of automatic propagation of VLAN information are: VTP and GVRP. Both protocols provide similar functionality:

1. VTP is a proprietary protocol from Cisco. Which is great for distributing VLAN information between switches, so-long as it's an all Cisco network, things are great.
2. GVRP is a standards based solution, but suffers from a less widespread support, some vendors such as Cisco do not support GVRP (only on the old CatOS)

Either can work find if you only have a single vendor of switch to manage, however in a mixed environment you will likely need a SNMP Manamagent utility that can synchronize between the two, as there doesn't seem to be a Layer-2-protcol based solution, so keep your eyes open for plug-in's for your management applications, or support within the application for VLAN synchronization.
