1.4 Typical MSTP Configuration Example
I. Networking requirement
MSTP provides different forwarding paths for packets of different VLANs. The
configurations are as follows: all the switches in the network belong to the same MST
domain, packets of VLAN 10 travels along instance 1, packets of VLAN 30 travels along
instance 3, packets of VLAN 40 travels along instance 0.
In the following network diagram, Switch A and Switch B are devices of the distribution
layer, Switch C and Switch D are devices of the access layer. VLAN 10 and 30 function
at the distribution and access layers, and VLAN 40 functions at the access layer only.
So the root of instance 1 can be configured as Switch A, root of instance 3 can be
Switch B, and root of instance 4 can be Switch C.

 Note:
The explanations on the above figure which goes like ”permit: XXXX” means that
packets of these VLANs are permitted to pass.
