   Code Block
   mkdir odu_high cd odu_high git clone "https://gerrit.o-ran-sc.org/r/o-du/l2"

   
   

3. Compilation of O-DU

   Code Block
   cd odu_high/l2/build/odu make clean_odu odu MACHINE=BIT64 MODE=FDD

   
   

4. Compilation of CU Stub

   Code Block
   cd odu_high/l2/build/odu make clean_cu cu_stub NODE=TEST_STUB MACHINE=BIT64 MODE=FDD

   
   

5. Compilation of RIC Stub

   
   

   Code Block
   cd odu_high/l2/build/odu make clean_ric ric_stub NODE=TEST_STUB MACHINE=BIT64 MODE=FDD

   
   

6. Execution - Assign IP addresses

   Code Block
   ifconfig <interface name>:ODU “192.168.130.81” ifconfig <interface name>:CU_STUB “192.168.130.82” ifconfig <interface name>:RIC_STUB “192.168.130.80”

   
   

7. Running CU Stub

   Code Block
   cd odu_high/l2/bin/cu_stub sudo ./cu_stub

   
   

8. Running RIC Stub

9. 
   

   Code Block
   cd odu_high/l2/bin/ric_stub sudo ./ric_stub

   
   

10. Running O-DU

    Code Block
    cd odu_high/l2/bin/odu sudo ./odu

    Note:

    1. Each of the above binaries must be run in separate terminals
