Hi there,
My setup as below:
sw1 -----sw2
sw1 and sw2 are cisco 3560
sw1 root bridge for vlan 1-20
sw2 root bridge for vlan 20-40
sw1 pvst
sw2 mst
trunk conf
switchport trunk enca dot1q
sw mode trunk
sw trunk allowed vlan 1,3,6
sw2 mst config
instance 0 vlan 1,3,6
instance 1 vlan all exepct above
and when i enable the trunk i got error and link goes to blocking mode
%SPANTREE-2-PVSTSIM_FAIL: Blocking root port Gi0/24: Inconsitent inferior PVST BPDU received on VLAN 4, claiming root 24580:0022.55bb.1500
anything i am missing in my config to get this to work ?
