Switch 4 is connected to Switch 1. After root protection is configured on interface
Switch 4 will send superior BPDUs that will trigger root protection on interface
A spanning tree topology contains ports that have specific roles:
The root port is responsible for forwarding data to the root bridge.
The alternate port is a standby port for the root port. When a root port goes down, the
alternate port becomes the active root port.
The designated port forwards data to the downstream network segment or device.
This configuration example uses an RSTP topology. However, you also can configure
root protection for STP or MSTP topologies at the [
To configure root protection on an interface:
To quickly configure root protection on interface
and paste it into the switch terminal window:
[edit]
set protocols rstp interface ge-0/0/7 no-root-port
To configure root protection:
Configure interface
1. ge-0/0/7
[edit protocols rstp]
user@switch#
set interface ge-0/0/7
Check the results of the configuration:
user@switch> show configuration protocols rstp
interface ge-0/0/7 {
no-root-port;
}
