On the other hand if you don't want to look/know who is the root, there is
nothing wrong in configuring the port priority on both switches. That's what
the author did,

Hi Guys,

If SW1 is root for vlan 100, you can give either port priority on SW1 or
port cost on SW2. Anyway you have to configure only on one switch. If you
don't configure any thing vlan traffic will passed through lowest port ID.

Yes, port priority is needed on one side only. Try it and it should work.

The requiement is to configure the sw1 and sw2 such that you will have the
traffic related to vlan_100 pass primarily through fa0/15 trunk port
........(pg. 371)

The solution on pg. 371 is the use of spanning-tree vlan port-priority
command on both sides (both trunks).

My question is why it need to be configured on both sides. If I configure it
only on sw1, will it still work?

PD
