- Add GraphQL query vrf_intent.gql: queries InfraVRFDeviceAssignment by device name, returning device-specific RD, VRF attributes (name, description, l3vni), and both device-level and VRF-level import/export route targets for fallback logic - Add Jinja2 template vrf_yang.j2: renders a JSON array of VRF config objects with RD fallback (device → VRF-level) and RT merge logic (device-level if present, otherwise VRF-level); all optional relationships guarded with 'is defined and is not none' checks - Update .infrahub.yml: register vrf_intent query and vrf_yang_transform - Add unit test fixtures for leaf3: input.json (mock GraphQL response) and output.json (expected rendered JSON array) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

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
