VTP3 and MST instance propagation.
What do i need to configure so the server can push MST instance configuration to the clients.
I configured vtp domain, changed to version 3 on all switches.
added
spanning-tree mst
spanning-tree mst configuration
revision1
name MST1
on all switches and instance is still not propagated. Not sure how VTP can push it. Do i need more config?
Thanks

Hi Qomat,
I think you are missing something here, please try configuring vtp specific command for mst as given below:
Rack1Sw2(config)#vtp mode server mst
Setting device to VTP Server mode for MST.
Rack1Sw2#sh vtp status
VTP Version capable : 1 to 3
VTP version running : 3
VTP Domain Name : ccie
VTP Pruning Mode : Disabled
VTP Traps Generation : Disabled
Device ID : 001e.bd06.0300
Apart from the usual usual output for VTP configuration, you should also see the following output for MST.
Feature MST:
--------------
VTP Operating Mode : Server
Configuration Revision : 0
Primary ID : 0000.0000.0000
Primary Description :
MD5 digest :
Feature UNKNOWN:
--------------
VTP Operating Mode : Transparent
Hope this helps!
Hi,
Have you mapped exactly the same vlans in to this instance on all switches ? If not I think you need to do that first...
Thanks
Thanks.
I think i was missing that command.
Also my server although it was only one server in the domain wasn't the authorative to push updates. Forgot the message (kind of it's not primary) I pushed it with some vtp mode server primary command and if i had this command u mention it probably work.
Whole point of my excerice was to push it not define it per switch.
Thanks though
After learning more about VTP v3, I had the same question about the MST enhancement...
Besides changing the VTP mode to vtp mode server mst you also have to go on the VTP MST Server and make it the primary MST server by issuing the command vtp primary mst in order for the MST config to propagate out to other switches....
