Hi Marko, Seeing this msg on sw1 with that debug. I forced them to trunk. But, still same issue. Please, let me know.

The transparent switch is passing on the messages *if* STP was converged when the announcement happens. One thing that I notice is that your trunks on SW1 are "dynamic desirable". Even though this shouldn't have anything to do with it since their operational mode is trunking - have you tried actually forcing trunks between switches? One last thing, what output do you get on SW1 when you enable "debug sw-vlan vtp events" and create a new VLAN on SW2 and exit from VLAN configuration mode? -- Marko Milivojevic - CCIE #18427 (SP R&S) Senior CCIE Instructor - IPexpert On Thu, Mar 15, 2012 at 14:57, karthk kumar <[email protected]> wrote: > Hi Marko, > > sh output posted below already for sw1.
