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.
Explanation:
· 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.http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/15.1SY/config_guide/sup2T/vtp.pd f
