After implementing VTP, the extended VLANs are not being propagated to other VTP switches. What should be configured for extended VLANs?
| A. |
VTP does not support extended VLANs and should be manually added to all switches. | |
| B. |
Enable VTP version 3, which supports extended VLAN propagation. | |
| C. |
VTP authentication is required when using extended VLANs because of their ability to cause network instability. | |
| D. |
Ensure that all switches run the same Cisco IOS version. Extended VLANs will not propagate to different IOS versions when extended VLANs are in use. |
* VTP version 1 and VTP version 2 do not propagate configuration information for extended-range VLANs (VLAN numbers 1006 to 4094). You must configure extended-range VLANs manually on each network device.
* VTP version 3 supports extended-range VLANs (VLAN numbers 1006 to 4094). If you convert from VTP version 3 to VTP version 2, the VLANs in the range 1006 to 4094 are removed from VTP control.
