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 [
To configure BPDU protection on two access interfaces:
To quickly configure BPDU protection on Switch 2, copy the following commands and
paste them into the switch terminal window:
