1.I have two switches connected together with two cables,Switch A is the root bridge for my vlan 2 traffic,so both ports are in designated fowarding. I want my traffic to preffer one of the port over the other, so I reduced the priority for vlan 2 on the port on switch A.
My question is ,do I need to reduce the priority at switch B too? Does this applies to port-cost too.
2. In a switched network with a root bridge for many spanning-tree vlan instance,will traffic from one leaf switch to another leaf switch on same vlan ,go the root bridge first
