Table 23 on page 221 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 uses RSTP topology. You also can configure BPDU protection
for MSTP topologies at the [
To configure BPDU protection on two access interfaces:
Quickly configure RSTP on the two Switch 2 interfaces, and then configure BPDU
protection on all edge ports on Switch 2 by copying the following commands and pasting
them into the switch terminal window:
NOTE: This example configures BPDU protection on specific interfaces.
Starting with Junos OS Release 15.1 for EX Series and QFX Series switches
with support for the Enhanced Layer 2 Software (ELS) configuration style,
you can also configure BPDU protection globally on all spanning tree
interfaces. See
on page 230 for additional information.
