Re: VTP Server and Transparent

Hi

As long as if there is no harm by configuring 1-4094 and hope it's accept
by CCIE exam as a valid answer we should not over think on this.

What I believe even though we have given for full range(1-4094), vtp
server only cares about 1-1005 because that its capacity. Its matter of why
Cisco switches are accepting full range on vtp server mode? or may be its
two different functionalities or could be a bug ?

We all here to learn.And it is really cool and fun to learn like this :)

Thanks again to all of you..

Don.
