The system sends keepalives every 1 second by default. In congested backplane scenarios, you can adjust:

set chassis redundancy ren-keepalive-threshold 500
set chassis redundancy ren-keepalive-interval 2000

But be warned: Changing these without JTAC guidance can cause false failovers. The Juniper Ren 2 link is a foundational

The core of this review focuses on the "R2" software release. In Juniper nomenclature, "R2" refers to the second maintenance release of a major version. The 15.1R2 build was significant because it matured the Juniper Fusion architecture.

1. Juniper Fusion Architecture (JFA) The standout feature introduced and stabilized in R2 builds was Juniper Fusion. This allows the EX4300 to act as a "Satellite" device to a larger "Aggregation" switch (like an EX9200).

2. Automation and SDN Readiness The 15.1R2 release enhanced support for Junos Space and native automation scripts.

3. Stability and Bugs While "R2" releases are generally considered more stable than the initial ".0" releases, the 15.1R2 build had a mixed reputation during its prime.
