VTP pruning with VTPv3

Jacob Zartmann

Hi,

 

I deployed VTPv3 today on a couple of switches. Small site for testing :)

I discovered that I could enable VTP pruning without being the primary server. And this change did not spread VTP domain wide. I had to enable VTP pruning on all switches in the VTP domain. This behaviour is very different from VTP v1 + v2.

 

I haven't found out the reason why it is like that. Neither have I found the documentation on this behaviour.

 

Can anyone demystify this?

Thanks

Hi Jacob,

I've tested this in a virtual environment and my observations seem to confirm your findings. Quite frankly, I do not know why this is the case. It could theoretically be a bug or an overlooked "feature". Sadly, I do not have any way of finding out.

Best regards,
Peter
