I am seeing some STP wierdness from a Nexus 9396 (surprise, surprise, I know).
I can't figure out why it's blocking one VLAN on a trunk to a Juniper switch,
scea-phx-core1# sh span vl 3013
VLAN3013
Spanning tree enabled protocol rstp
Root ID Priority 64453
Address 0023.04ee.be01
This bridge is the root

I don't understand a lot of things going on here. It claims to be root, but
then it's blocking ports? And how can you have a backup when this is the only
port on the VLAN?
