Refurbished Cisco 2921 Integrated Services Router

Enterprise-grade modular router with three Gigabit Ethernet ports, dual USB 2.0, up to 2GB RAM, IPv4/IPv6 support, and extensive WAN/VPN capability — from $59 inc-GST with a 3-month warranty from Reboot IT.

Why Choose the Cisco 2921 Router?

  • Three Gigabit Ethernet Ports: Dual-purpose WAN/LAN ports support flexible network topologies — connect multiple ISPs, DMZ segments, or internal networks simultaneously.
  • Extensive Module Expansion: Four onboard service module slots support HWIC, NME, SM, and PVDM modules for DSL, T1/E1, VoIP, and hardware encryption acceleration.
  • Up to 2GB RAM: Generous memory headroom for complex routing tables, QoS policies, and Cisco IOS feature sets including advanced security and VPN.
  • IPv4 and IPv6 Support: Future-proof dual-stack routing capability supports both current and next-generation IP infrastructure without additional licensing.
  • Hardware VPN Acceleration: Built-in crypto engine supports IPsec and SSL VPN tunnels at wire speed — secure site-to-site and remote access VPNs for business connectivity.
  • Proven Enterprise Platform: The Cisco 2900 series is a well-documented, widely deployed router with extensive community support and Cisco IOS compatibility.

Performance in Business Networks

The Cisco 2921 serves as a reliable branch or small office router for organisations running Cisco IOS-based networks. Its modular architecture lets you add serial WAN interfaces, T1/E1 ports, or voice DSP modules without replacing the base unit. The hardware encryption engine handles VPN tunnel termination without impacting routing performance, making it suitable for distributed offices connecting back to a central site over the internet.

Network administrators familiar with Cisco IOS will appreciate the consistent CLI experience, extensive feature set, and compatibility with Cisco's management tools. The 2921 supports advanced QoS for voice prioritisation, OSPF/EIGRP/BGP dynamic routing, and Network Address Translation for typical edge deployments.

Frequently Asked Questions

Does this router come with a Cisco IOS license?

The unit ships with the IOS image installed at time of refurbishment. Specific feature set licensing (Security, Data, UC) depends on the IOS version present. Verify required feature sets with Cisco's licensing portal if needed.

Can I add WAN interface cards for DSL or serial connections?

Yes — the HWIC slots accept a wide range of High-Speed WAN Interface Cards for ADSL, VDSL, T1/E1, serial, and other WAN interfaces. Check Cisco's compatibility matrix for specific HWIC models.

Is this suitable as a lab router for CCNA/CCNP study?

Yes — the 2921 is an excellent study router supporting a broad IOS feature set relevant to CCNA and CCNP curriculum including OSPF, EIGRP, BGP, VPN, QoS, and security features.
