-## gRPC Client DNS RoundRobin {#grpc-client-dns-roundrobin}
-
-**gRPC Client DNS RoundRobin** enables DNS-based round-robin load balancing. This method uses DNS to resolve endpoints and distributes load balancing of _all_ addresses returned by the DNS record client side. **Do not disable** unless you have a specific use case.

 ## gRPC Client Timeout {#grpc-client-timeout}
 
 **gRPC Client Timeout** sets the maximum time before canceling an upstream gRPC request. During transient failures, the proxy will retry upstream servers for this duration. You should leave this high enough to handle backend service restart and rediscovery so that client requests do not fail.
