EOS SDK and its RPC counterpart traditionally offer two separate calls for configuring static routes. These calls are ip_route_set/ip_route_via_set and mpls_route_set/mpls_route_via_set. When calling the SDK API directly the calling latency is negligible, since it is a simple function call. However, the time of each of those calls can become a considerable factor with the adoption of RPC. To reduce the overall latency associated with creating and updating numerous routes, EOS SDK RPC now supports bulk calls.

This feature provides a continuous, live, stream of ingress counters for Policy-Based Routing (PBR) rules in terms of bytes and packets. It is implemented as a special call in EosSdkRpc and follows this definition:
