Configuring Rapid Transition
Configuration prerequisites
As shown in Figure 1-8 , a H3C series switch is connected to another manufacturer's switch. The former
operates as the downstream switch, and the latter operates as the upstream switch. The network
operates normally.
The upstream switch is running a proprietary spanning tree protocol that is similar to RSTP in the way to
implement rapid transition on designated ports. Port 1 is the designated port.
The downstream H3C switch is running MSTP. Port 2 is the root port.
