+
+## Reproduce
+
+GKE Gateway conformance report can be reproduced by the following steps.
+
+1. create a GKE cluster with Gateway API enabled (the minimum cluster version that supports v1.3.0 CRD is `1.33.2-gke.1335000`)
+
+```
+gcloud container clusters create "${cluster_name}" --gateway-api=standard --location="${location}"
+```
+
+2. create a proxy-only subnet if using a regional Gateway following [guide](https://cloud.google.com/kubernetes-engine/docs/how-to/deploying-gateways#configure_a_proxy-only_subnet)
+
+3. run the following command from within the [GKE Gateway repo](https://github.com/GoogleCloudPlatform/gke-gateway-api)
+
+```
+go test ./conformance -run TestConformance -v -timeout=3h -args \
+    --gateway-class=gke-l7-global-external-managed \
+    --conformance-profiles=GATEWAY-HTTP \
+    --organization=GKE \
+    --project=gke-gateway \
+    --url=https://cloud.google.com/kubernetes-engine/docs/concepts/gateway-api \
+    --version=1.33.4-gke.1134000 \
+    [email protected] \
+    --report-output="/path/to/report"
+```
+
+or run a single conformance test case
+
+```
+go test ./conformance -run TestConformance -v -args \
+    --gateway-class=gke-l7-global-external-managed \
+    --run-test=HTTPRouteRequestMirror
+```
+
+Note: the repro result can be flaky in some cases because the conformance framework doesn't isolate test cases enough.
