#### Step 1: Edit the RRU configuration file (`start from ~/openairinterface5g/targets/PROJECTS/GENERIC-LTE-EPC/CONF/rru_oaisim.conf`)
|
|
|
|
|
|
The file is edited appropriately with respect to Figure 2:
|
|
|
* MAC address of RRU is `24:f5:aa:e1:46:01` and Ethernet interface name is `eth0`
|
|
|
* MAC address of RCC towards RRU is `24:f5:aa:e1:4e:0c`
|
|
|
* RRU will have a `USRPB210` attached to it
|
|
|
|
|
|
It is assumed that `NGFI_IF4.5` will be used with `RAW` ETHERNET transport. Using this information the configuration file of RRU is edited as follows:
