Configuration Roadmap
The configuration roadmap is as follows:
1. Configure basic RSTP functions, including:
(1) Configure the RSTP mode for the ring network.
(2) Configure primary and secondary root bridges.
(3) Set path costs for ports in each MSTI to block certain ports.
(4) Enable RSTP to eliminate loops.
NOTE
RSTP is not required on the interfaces connected to terminals because these interfaces do not
need to participate in RSTP calculation.
2. Configure RSTP protection functions, for example, root protection on a designated port of
a root bridge in each MSTI.
Data Preparation
To complete the configuration, you need the following data:
l GE interface number, as shown in Figure 8-4
l Primary root bridge SwitchA and secondary root bridge Switch
