- Set a different system ID and unicast address in
                        /legato/systems/current/appsWriteable/tafSomeipGWSvc/tafSomeipGWSvc.json
                    for each TelAF system.
- Refer to [RPC JSON configuration](https://docs.qualcomm.com/doc/80-41102-1/topic/rpc-json-configuration.html) to declare the RPC systems
                    and RPC services in
                        /legato/systems/current/appsWriteable/tafRpcProxy/taf\_rpc.json
                    file for each TelAF system. Note that the same taf\_rpc.json
                    file must be applied for all TelAF systems.
- Create a route entry for the multicast address 224.0.0.1 on each TelAF
                    system.
- Run `telaf restart` on each TelAF system to make the new
                    configuration take effect.
- Refer to [RPC binding](https://docs.qualcomm.com/doc/80-41102-1/topic/rpc-binding.html) or [Bind the same service on both local and remote systems](https://docs.qualcomm.com/doc/80-41102-1/topic/bind-the-same-service-on-both-local-and-remote-systems.html) for
                    application to bind RPC services.
