Configuration Rule
VTP v2 mode is enabled, and you 
are configuring a TrCRF VLAN 
media type.
Specify a parent VLAN ID of a TrBRF that already exists in the 
database.
Specify a ring number. Do not leave this field blank.
Specify unique ring numbers when TrCRF VLANs have the same 
parent VLAN ID. Only one backup concentrator relay function 
(CRF) can be enabled.
VTP v2 mode is enabled, and you 
are configuring VLANs other than 
TrCRF media type.
Do not specify a backup CRF.
VTP v2 mode is enabled, and you 
are configuring a TrBRF VLAN 
media type.
Specify a bridge number. Do not leave this field blank.
