Configure the port mode for the interfaces:

[edit interfaces]
user@switch4# set ge-0/0/23 unit 0 family ethernet-switching interface-mode trunk
user@switch4# set ge-0/0/19 unit 0 family ethernet-switching interface-mode trunk
Configure RSTP on the switch:

[edit protocols]
user@switch4# rstp bridge-priority 16k

If Switch 4 includes dual Routing Engines, configure nonstop bridging. To configure NSB
on Switch 4:
Enable graceful Routing Engine switchover (GRES):
1.
[edit chassis redundancy]
user@switch4# set graceful-switchover
Configure the switch to always synchronize configuration changes between the
2.
Routing Engines:
[edit system]
user@switch4# set commit synchronize
If you try to commit a configuration in which nonstop bridging is configured but
synchronization of configuration changes is not configured, the configuration is not
committed.
Enable nonstop bridging:
3.
[edit protocols layer2-control]
user@switch4# set nonstop-bridging
NOTE: This process enables NSB for all NSB-supported Layer 2
protocols on the switch, including RSTP.
Check the results of the configuration:
