VTP Version 2 feature question
So in the Catalyst 3560 configuration guide on page 13-4 it states the following regarding the VTP Version 2 protocol features:
Unrecognized Type-Length-Value (TLV) support—A VTP server or client propagates configuration
changes to its other trunks, even for TLVs it is not able to parse. The unrecognized TLV is saved in
NVRAM when the switch is operating in VTP server mode.
Does anyone know of an example where this would be applicable? I'm trying to understand where an unrecognized TLV would come into play.
