[c-nsp] VTP, extended vlans and 6500/Sup720s

[Masood Ahmad Shah]

Well, vtp v3 is compatible with vtp v1,2 but you can't use vtp v1 with vtp
version 2 and vice versa...

To get advantage of extended vlans transfer you need to have vtp version
3...

Subject: [c-nsp] VTP, extended vlans and 6500/Sup720s



So, I have existing gear running CatOS and VTPv3, and new gear that is 
Sup720s running 12.2.18SXF.

I need IOS on the 720s in order to use the DFCs, but VTPv3 only seems to 
be available for SRC on the 7600...


The 720s and SUP2 systems form the redundant core and core fanout and 
need to maintain the exact same vlan set.  Everything downstream of this 
group is distribution through edge and is not VTP enabled.


I can drop back to VTPv2 for all, but this leaves be with no sync of 
vlans > 1005.


Looking for suggestions as to vlan management tools/etc that could be 
used to keep the extended range vlans in sync, and am surprised that I 
have not found anything.  All I need to be able to do is

Keep a central list and push to 12 systems.

OR

Read one system and sync the others.


I would love to find a via SNMP script that does a one sync including 
removal.


Suggestions?  (Or is it time to crack the perl books?).

Thanks


The correct solution is Cisco releasing vtpv3 for 6500 IOS, but I have 
been hearing "any time now" for about 2 years...
