1.1 The "advipservicesk9" Feature Set Explained

The advipservices set is one of the most feature-rich images for the Cisco 2691 platform. It includes:

  • 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)

⚠️ Note: The "k9" suffix indicates that this image contains strong encryption. In many jurisdictions, Cisco required end-user export declarations to obtain such images.

4.1 Network Emulation (GNS3 / EVE-NG)

This image is a gold standard for virtual labs because:

  • It supports a wide range of routing protocols (BGP, OSPF, EIGRP) without consuming excessive CPU.
  • It can emulate MPLS L3 VPNs for CCNP Service Provider studies.
  • The 2691 platform in GNS3 is stable and has predictable resource usage.
