C2691-advipservicesk9-mz.124-17.image File

The Cisco IOS image C2691-advipservicesk9-mz.124-17.image is a stable 12.4 release for the Cisco 2691 router, offering advanced IP services including BGP, OSPF, EIGRP, and IPv6 support. Widely used in simulation tools like GNS3, it requires 192 MB DRAM and 48 MB Flash, making it ideal for CCNA and CCNP certification labs. For more details on this software package, visit Cisco.

3. Hardware & software compatibility

• Router model: Cisco 2691 (part of 2600XM/2600 series family).
• Memory/Flash requirements: Typical 12.4 images require sufficient DRAM (often 64–128+ MB depending on feature usage) and flash (commonly 16–32 MB or larger for additional files). Exact minima depend on subversion and optional features (crypto, voice).
• Supported modules: WAN interface cards (WIC, VWIC), NM/PA modules where physically compatible. Some advanced features (e.g., crypto acceleration) may depend on available hardware and IOS build options.
• Licensing: Historically, feature availability tied to image name; activation sometimes via Smart Licensing or traditional license tokens on newer platforms, but 2691-era licensing was simpler—image selection determined features. Confirm licensing for production use.

Understanding the Cisco C2691-advipservicesk9-mz.124-17.image: A Deep Dive into Legacy IOS

6. Typical Use Cases

This image is not for production today (EOL since 2010s) but excellent for: C2691-advipservicesk9-mz.124-17.image

• CCNP / CCIE labbing (Routing, MPLS, VPN, QoS)
• Legacy network simulation (GNS3, EVE-NG, CML) – this image is very common in GNS3 image repositories
• Testing VPN interoperability with old devices
• Learning IOS 12.4 CLI

6.2 Loading in GNS3

1. Add the image to GNS3’s IOS router template.
2. Allocate 256 MB RAM for best performance.
3. Set the idle-pc value (usually around 0x6044a8d0 for this image) to reduce CPU usage.

2. Feature Set: advipservicesk9

This is a high-end feature set for the 2691 platform. It includes: The Cisco IOS image C2691-advipservicesk9-mz

• Advanced IP routing: OSPF, EIGRP, BGP, IS-IS, RIP v1/v2, static routes
• Multicast: PIM (Sparse/Dense Mode), IGMP, MSDP
• Quality of Service (QoS): CBWFQ, LLQ, policing, shaping, NBAR
• Security:
  • 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)
• IPv6: Routing (OSPFv3, RIPng, static), tunneling, basic transition mechanisms
• MPLS: Label switching, VPNs (L3VPN, AToM) – very useful for labbing
• Management: SNMP, NetFlow, Syslog, SSH (requires crypto), HTTP/HTTPS server

Not included compared to advipservicesk9_wan or enterprise? On 2691, advipservicesk9 is near-maximum. You won't get things like c2691-ipvoice features (VoIP gateways) or c2691-advsecurity (older subset). Cisco IOS Image C2691-ADVIPSERVICESK9-MZ
