Options from here
The Juniper EX Series EX4300 is still supported (to Dec 2031). 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 and no maintenance, and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the role the asset plays.
