NOTE: This example uses Junos OS for EX Series switches with support for
the Enhanced Layer 2 Software (ELS) configuration style. If your switch runs
software that does not support ELS, see Example: Faster Convergence and
Improved Network Stability with RSTP on EX Series Switches. For ELS details,
see Getting Started with Enhanced Layer 2 Software.
EX Series switches use Rapid Spanning Tree Protocol (RSTP) by default to provide a
loop-free topology.
When switches that support redundant Routing Engines use RSTP, it is important to keep
RSTP synchronized on both Routing Engines so that no loss of service occurs after a
Routing Engine switchover. Nonstop bridging protocol keeps Routing Engines synchronized.
This example describes how to configure RSTP and NSB on four EX Series switches:
