I have set up a lab to test migratation from PVST to MST. The lab will use VLAN 1-1005; private VLANs are not used. For the first test phase, all active VLANs will be placed in Instance 1 (no load balancing).
I have read some conflicting information on best practice for configuring MST and I'm hoping someone can offer their opinion: One method says to configure "as few VLANs as possible" in Instance 0 and as many as requird in the remaining Instances. For Example: spanning-tree mode mst spanning-tree configuration name Cisco version 10 instance 1 vlan 1-4094 spanning-tree mst 0-1 priority 24576 (MST0 - no vlan; MST1 - vlan 1-4094) The other method says to put only the used VLANs in Instance 1-64, leaving the non-used VLANs in Instance 0. For Example: spanning-tree mode mst spanning-tree configuration name Cisco version 10 instance 1 vlan 1-1005 spanning-tree mst 0-1 priority 24576 (MST0 - 1006-4094; MST1 - vlan 1-1005) Which configuration would be "more correct"? Does anyone have a good link where I can get more information?
