The best way to do this , for instance, is to have CatA be thr root bridge for vlan2, and CatB the root bridge for vlan3.
When you do this, CatC will use CatA trunk/channel for vlan 2 and CatB trunk/channel for vlan3. Remember the STP decision sequence: 1. Lowest Root BID 2. Lowest Path Cost to Root bridge 3. Lowest Sender BID 4.
