Hello, I have problem when following this tutorial https://docs.srsran.com/projects/project/en/latest/tutorials/source/srsUE/source/index.html#zeromq-based-setup. At step Testing the Network and Routing Configuration. I cannot add route as it is already presented.

sudo ip ro add 10.45.0.0/16 via 10.53.1.2
RTNETLINK answers: File exists

my route is below.

$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

My config is open5gs on docker of srsRAN_Project, gNB from srsRAN_Project, and ue from srsRAN4G. This is zmq based with no actual radio or UE.
My system runs well, but I stuck at this step.

Thank you very much.

you probably have Open5gs installed from source, right?
please check this section: https://docs.srsran.com/projects/project/en/latest/tutorials/source/srsUE/source/index.html#nd-open5gs-instance-installed-manually
