Cisco ISR 2900 Series End-of-Life & EOSL Dates

PAST VENDOR SUPPORTCisco ended support in April 2025.

The Cisco ISR 2900 Series is a router in Cisco's ISR product line. End-of-sale and end-of-service-life dates are listed by part number below, each linked to the Cisco EOL bulletin.

Every tracked Cisco ISR 2900 Series SKU group is past Cisco end of service life (last group Apr 2025). Units in production should be treated as unsupported. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure. Cisco’s named migration path: C1-CISCO4321.

Why this score
  • Past end of service life 60 months ago
  • Vendor-published date, source-linked
  • Vendor-named replacement / migration path available
  • Category: router

Support-lifecycle timing and source confidence only. Higher means more runway. It is not a risk, safety or compliance rating. How it is calculated

Figure 1. Cisco issues no software maintenance and no security fixes for this product. Third-party maintenance, spares or replacement are the paths from here. EOSL.ai sells none of them and takes no placement fee.
Figure 2. The 2900 Series against 5 other models in Cisco ISR. Each bar runs from the earliest milestone Cisco publishes for that model, which is first availability where it gives one and end of sale otherwise, to its last date of support. The vertical rule is today; bars entirely to its left are past support.

Options from here

The Cisco ISR 2900 Series is past Cisco end of service life. These are the paths teams take from here:

Third-party maintenance

Keep it in production past the OEM cutoff with an independent maintainer.

Pre-stock spares

Buy spares now, while units still circulate on the secondary market. Current eBay listings for ISR 2900 Series ↗

Plan replacement

It is unsupported today. Set a migration timeline and budget.

Run to failure

Low-criticality role: document the risk, harden backups, retire on your terms.

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.
