Configure Extended VLANs, VTP and DTP With Packet Tracert


Background / Scenario

In this lab you will configure a switched environment where trunks are negotiated and formed via DTP, and
VLAN information is propagated automatically through a VTP domain. You will create an extended VLAN and
to add it to the VTP domain.

Scalability and management are two critical considerations when creating a large network. VTP and DTP are
protocols that improve management and scalability. Extended VLANs enable better scalability in large
environments by extending the number of VLANs that can be configured in a switch. VLAN Trunking Protocol
(VTP) allows the switches to automatically communicate VLAN information, improving management and
scalability. Dynamic Trunking Protocol (DTP) allows the switches to automatically negotiate and establish
trunk links. DTP also improves scalability.
