High CPU utilization or congestion on the internal management path can lead to lag when using the Junos CLI.
Sometimes, a configuration is invalid.
Ensures both RE cards are recognized, active data synchronization is running, and slot states show proper Primary/Backup designations. show interfaces aggregated-ethernet link-protection ae0 Use code with caution.
The term typically references high-availability configurations involving a secondary Routing Engine (RE) or node link, or the implementation of Layer 2 link aggregation over dual redundant interfaces to guarantee carrier-grade network resilience.

The direct internal or external fabric path running real-time state synchronization via Nonstop Active Routing (NSR) or Graceful Restart (GR).
If you are currently setting up a specific architecture, let me know:

Look for the line: . If it says "OK" or "Ready", your REN 2 link is healthy. If it says "Unreachable" or "Check Ethernet," you have a problem.
I’d be glad to summarize, verify, or discuss why it’s interesting.
As data center architectures scale, standard Layer 2 configurations are shifting toward hybrid models to support AI and high-performance computing workloads. Layer 2 Networking | Junos OS - Juniper Networks If you are currently setting up a specific
