I've configured my core switch to be the primary root for 3 vlans. On 2 vlans, everything seems to be showing up fine, on a third vlan I have "Spanning tree instance(s) for vlan X does not exist." Does someone know what this could be from?
In addition to what the previous posters stated I would add if you have a trunk in which a VLAN is active that would cause the STP instance for that VLAN to be enabled as well. Since you already had active trunks, I assume your trunk must have been filtering/blocking the VLAN in question and that probably was the cause of the problem.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
