Switch 2 has RSTP disabled and has these access ports that require BPDU
protection:
ge-0/0/5
ge-0/0/6
CAUTION: When configuring BPDU protection on a non-STP configured
switch connected to an STP-configured switch, be careful that you do not
configure BPDU protection on
being received on interfaces (such as a trunk interface) that should be
receiving BPDUs from an STP-configured switch.
To configure BPDU protection on the interfaces:
To quickly configure BPDU protection on Switch 2, copy the following commands and
paste them into the switch terminal window:
[edit]
set ethernet-switching-options bpdu-block interface ge-0/0/5
set ethernet-switching-options bpdu-block interface ge-0/0/6
To configure BPDU protection:
Configure interface
ge-0/0/5
1.
[edit ethernet-switching-options]
user@switch# set bpdu-block interface ge-0/0/5
user@switch# set bpdu-block interface ge-0/0/6
Check the results of the configuration:
user@switch> show ethernet-switching-options
bpdu-block {
interface ge-0/0/5.0;
interface ge-0/0/6.0;
}
To confirm that the configuration is working properly, perform these tasks:
