Multiple matching destinations via regex

1

Hi,

We have multiple destinations depending on what a header value is in gRPC. However these regexes match both routes, and all traffic seems to be going to subset v1-0-205. Say we have a header value of 12.0.1.47, we want that to go to subset v1-0-192. Is there a way we can have an order of preference?

routes:
          - match:
              - headers:
                  content-api-version:
                    regex: ^12\.[0-9]+\.[0-9]+\.[0-9]+$
            route:
              - destination:
                  subset: v1-0-205
          - match:
              - headers:
                  content-api-version:
                    regex: ^12\.0\.(0\.[0-9]+|1\.([0-9]|[0-4][0-9]|5[0-4]))$
            route:
              - destination:
                  subset: v1-0-192

Thanks in advance for any input on this!
