Options from here
The Juniper EX Series EX4300 is still supported. Options to plan around, in rough priority:
Supported for now — track the end-of-service date and revisit at refresh planning.
Fold the eventual replacement into your multi-year budget.
Stay on a supported software train while under OEM support.
An option to extend life once the OEM cutoff nears.
Independent and informational — EOSL.ai sells no hardware or maintenance and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the asset's role.
