In a network containing switches with both GVRP and MSTP enabled, GVRP
packets are forwarded along the CIST. In this case, if you want to broadcast
packets of a specific VLAN through GVRP, be sure to map the VLAN to the CIST
when configuring the MSTP VLAN mapping table (the CIST of a network is
spanning tree instance 0).

Configuring the Path
Cost for a Port
The path cost parameter reflects the rate of the link connected to the port. For a
port on an MSTP-enabled switch, the path cost may be different in different
spanning tree instances. You can enable flows of different VLANs to travel along
different physical links by configuring appropriate path costs on ports, so that
VLAN-based load balancing can be implemented.
