question about VTP Config Revision number

major133major133 ✭
in CCNP General

 


hello everyone,


In a VTP example from lecture number= 40

 

VLAN Trunking Protocol (VTP)


into this example :-

sw-2#show vtp status

and you see into this picture we`ve into that sw-2 :


configuration revision = 0

Number of existing VLANS = 24



The video presenter stated that any deletions or creations to any other vlans into server mode , would cause the configuration revision to increment by 1


so why this number into this example = 0 ???

    Even if a VTP server has a number of existing VLANs (and a non-zero Configuration Revision number) that Config-Rev number will be reset to zero if the VTP Domain name is changed.

    I suspect that is what happened in that video.  Although 24-VLANs are present, with a Config-Rev of zero (and VTP Mode of Server) it could only mean that this switch recently had its VTP Domain Name modified.

    Hi Martinl

    The Configuration Number will change even if you edit the name of a vlan
