However, for education, lab practice, and niche legacy industrial environments, this image remains invaluable. It teaches the fundamentals of IP routing, MPLS, and VPN technologies without the complexity of modern unified architectures (like SD-WAN or Viptela). C2691-advipservicesk9-mz.124-17.image
- IPSec VPN (3DES, AES) – the "k9" indicates strong crypto
- GRE tunneling
- Zone-Based Firewall (ZBF)
- IOS IPS (Intrusion Prevention System – limited)
- Control Plane Policing (CoPP)

Cisco IOS Image C2691-ADVIPSERVICESK9-MZ.124-17 — Overview Paper
Abstract
This paper summarizes the Cisco IOS image named C2691-ADVIPSERVICESK9-MZ.124-17 for the Cisco 2691 router platform. It covers the image purpose and feature set, hardware/software compatibility, key capabilities (routing, switching, security, QoS, voice), licensing and image naming, typical deployment use cases, upgrade and migration considerations, configuration and troubleshooting notes, and security/maintenance recommendations.
After recovery, set proper boot system command.
- Advanced IP routing: OSPF, EIGRP, BGP, IS-IS, and RIP (v1 & v2)
- Multicast support: PIM, IGMP, and MSDP
- Quality of Service (QoS): Class-based weighted fair queuing (CBWFQ), low latency queuing (LLQ), traffic shaping, policing
- IP Services: NAT, DHCP server/relay, HSRP, VRRP, GLBP
- MPLS: Layer 3 MPLS VPN support (crucial for service provider labs)
- Security features: Zone-based firewall (ZBFW), IPS, control plane policing (CoPP)
- VPN technologies: GRE, IPsec with 3DES/AES (via the k9 encryption)
