You'll likely want to do something like:
- Use the gRPC field extraction filter to pull out the field and put it in the dynamic metadata for the request.
- Configure your routes to match on dynamic_metadata.

@tonya11en thanks for the suggestion.
I used the grpc_field_extraction filter and I can extract the needed field
I have created a dynamic_metadata under route match as follow
- name: local_service
domains: ["*"]
routes:
- match:
prefix: /path/
grpc: {}
dynamic_metadata:
- filter: envoy.filters.http.grpc_field_extraction
path:
- key: key1
value:
list_match:
one_of:
string_match:
exact: "value1"
route:
cluster: nrc_cluster1 ```
But my requests never match any route and fail.
anything wrong/missing with my config?

I had to add a lua filter to the config.
the lua filter that I added was failing and didn't do anything but somehow after adding the lua the route matching started to work.
I noticed Others had similar problem #19910 and might be related to route caching.
seems lua filter enforces a refresh to the route config
