VTP Vlan Trunking Protocol

VTP is the VLAN trunking protocol. It's used to disseminate uniform vlan information between switches over 802.1q or ISL trunks. It can also "prune" vlans, dynamically removing unneeded VLANs from trunks. This decreases unneeded frame flooding. VTP can eliminate outages thanks to the uniform VLAN configuration. But it can also cause outages if incorrect VLAN information is uniformly distributed. We also attempt a loopguard demonstration, but it doesn't work out well. We'll have to revisit the documentation because it's obvious loopguard is not acting as I expect.
