If Switch 3 includes dual Routing Engines, configure nonstop bridging. To configure NSB

user@switch3# set graceful-switchover
Configure the switch to always synchronize configuration changes between the
2.

[edit system]
user@switch3# set commit synchronize
If you try to commit a configuration in which nonstop bridging is configured but

Enable nonstop bridging:
3.
[edit protocols layer2-control]
user@switch3# 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:
