OS for EX Series Ethernet Switches, Release 10.3
This example shows you how to configure interface
as edge ports and to configure BPDU protection. When BPDU protection is enabled, the
interfaces will transition to a blocking state when BPDUs are received on them.

Figure 37: BPDU Protection Topology

Table 217 on page 1562 shows the components that will be configured for BPDU protection.
Settings
Switch 1 is connected to Switch 2 on a trunk interface.
Switch 2 has these access ports that require BPDU protection:
ge-0/0/5
ge-0/0/6
This configuration example is using an RSTP topology. You also can configure BPDU
protection for STP or MSTP topologies at the [
level.
