## Summary Implements Infrahub Jinja2 Transform for VRF/L3VNI configuration, generating structured JSON payloads from Infrahub intent data. Closes #21. ## What's included - **GraphQL query** (`transforms/queries/vrf_intent.gql`): Queries `InfraVRFDeviceAssignment` by device name, fetching VRF details, L3VNI, route targets, and device-specific route distinguisher - **Jinja2 transform** (`transforms/templates/vrf_yang.j2`): Renders VRF config payloads with defensive null handling (lessons learned from #20) - **`.infrahub.yml`** updated with the new query and transform definitions - **Tests** (`transforms/tests/vrf_yang/`) using correct Infrahub pytest format (`jinja2-transform-smoke` + `jinja2-transform-unit-render`) ## Validation All transforms render correctly: | Device | Expected | Result | |--------|----------|--------| | `leaf3` | VRF gold, RD `10.0.250.13:1`, L3VNI 100001 | ✅ | | `leaf7` | VRF gold, RD `10.0.250.17:1`, L3VNI 100001 | ✅ | | `leaf1` | Empty array (no VRF assignment) | ✅ | | `spine1` | Empty array (no VRF assignment) | ✅ | ## Usage ```bash # Local debugging infrahubctl render vrf_yang_transform device_name=leaf3 # API endpoint GET /api/transform/jinja2/vrf_yang_transform?device_name=leaf3 ``` ## Related - Depends on: #20 (base transforms infrastructure, already merged) - Reference: Arista EVPN Type-5 / L3VXLAN configuration from lab topology

vrf_yang.j2 — Produce a JSON array of VRF configuration objects.
|
|
|
|
Input: GraphQL response from vrf_intent query.
|
|
For each VRFDeviceAssignment, produce one VRF config entry with:
|
|
- device-specific RD (falls back to VRF-level RD if not set on assignment)
|
|
- L3VNI from the VRF's l3vni relationship
|
|
- import/export targets: device-level if present, otherwise VRF-level
