Iosxrv-k9-demo-5.2.2.ova [NEWEST ●]

IOS XR 5.2.2 introduced robust Segment Routing support. Try these commands:

router isis core
 address-family ipv4 unicast
  segment-routing mpls sr-prefer
  segment-routing mpls
 interface Loopback0
  prefix-sid index 100

Then verify with: show segment-routing mpls binding. iosxrv-k9-demo-5.2.2.ova

| Purpose | Works well? | Notes | |---------|-------------|-------| | CCIE SP v4/v5 labs | ✅ Yes | Many older workbooks use 5.x | | BGP/MPLS VPN control plane | ✅ Yes | Full control-plane support | | Segment Routing (SR-MPLS) | ⚠️ Partial | Basic SR works, but some 6.x features missing | | EVPN/VXLAN | ❌ No | Too old for proper EVPN | | Netconf/YANG dev | ✅ Yes | With older models | | Traffic testing | ❌ No | No real throughput | IOS XR 5

The first boot of IOS XRv is slow. It needs to initialize the filesystem and generate keys. Then verify with: show segment-routing mpls binding

Many candidates build topologies with 6–10 XRv routers in EVE-NG or GNS3 (after converting OVA to QCOW2). Version 5.2.2 is mature and stable, allowing candidates to master:

The XRv is a control plane virtual router. It uses the host CPU for packet forwarding, meaning it cannot achieve line-rate forwarding (e.g., 10Gbps). Expect a few hundred Mbps at best with simple routing.

Given that 5.2.2 is quite old, consider these better options today:
