Why are Extended Vlans Used?

Extended VLANs are VLANs within the range of1006 to4094. They are mainly used in service provider networks to allow the provisioning of number of customers.

In order to configure an extended VLAN you have to follow the guideline below:

• Extended VLANs are used just like normal VLANs; only different range.
• Extended VLANs must be configured on Switches that are in VTP Transparent mode only.
• Extended VLANs can not be configured using VLAN database mode (only configuration mode).
• Extended VLANs are saved in the configuration file.
