Xrv9k-fullk9-7.2.2 ((better)) | DELUXE – 2026 |

When working with the xrv9k-fullk9-7.2.2 image, you may encounter a few common issues:

However, the existence of this virtual router raises a philosophical question about the nature of networking in the cloud era. If a router is defined by its purpose (to forward packets and compute paths), and XRv9k does this perfectly in software, why do we still buy hardware? The answer lies in the word "fullk9." While the control plane is identical, the data plane is a simulation. A virtual router cannot forward 100 Gbps of traffic at line rate; it can only compute how that traffic would be forwarded. The 7.2.2 image is thus a ghost in the machine—it has the memory of a router, the logic of a router, but not the physical destiny.

: By default, unlicensed XRv 9000 images are rate-limited to 4. Common Issues No Interfaces in GNS3 Xrv9k-fullk9-7.2.2

According to documentation from the EVE-NG community, which is a popular platform for running this image, the recommended virtual resources are as follows:

Unlike legacy 32-bit IOS XR, the 64-bit architecture used in version 7.2.2 removes memory allocation limits per process. This allows the virtual router to leverage massive system RAM allocations, mapping efficiently to host hardware. The underlying architecture splits into two primary layers: When working with the xrv9k-fullk9-7

Comprehensive native and OpenConfig YANG model support for programmatic configuration via NETCONF and RESTCONF.

Based on community benchmarks from the "Routing Futures" group, here is how Xrv9k-fullk9-7.2.2 performs against its predecessor: A virtual router cannot forward 100 Gbps of

Due to the fullk9 designation, the image supports advanced protocol stacks, enabling comprehensive verification of complex network designs including EVPN-VXLAN, Segment Routing over IPv6 (SRv6) Traffic Engineering, and hierarchical Quality of Service (HQoS) architectures prior to physical hardware delivery. Operational Best Practices

While segment routing was introduced in earlier releases, version 7.2.2 delivers enhanced stability and features for both Segment Routing over MPLS (SR-MPLS) and Segment Routing over IPv6 (SRv6). This includes refined support for Segment Routing Flexible Algorithm (Flex-Algo), allowing operators to customize routing paths based on metrics like delay or exclusion of specific link types, which is essential for 5G network slicing. 3. Model-Driven Telemetry and Programmability

2. Continuous Integration and Continuous Deployment (CI/CD) Pipelines

Ensure your hypervisor config matches your virtual NIC types. Use virtio or e1000 drivers. In ESXi, ensure the vSwitch allows Promiscuous Mode, MAC Address Changes, and Forged Transmits.
