该教程参考了笔者之前在一台设备上部署基站和核心网的教程，为了在不同机器上部署核心网和基站，我们需要添加路由转发规则。
1. 核心网启动
oai-cn5g-fed/docker-compose$ docker-compose -f docker-compose-basic-vpp-nrf.yaml up -d
Creating mysql ... done
Creating oai-nrf ... done
Creating vpp-upf ... done
Creating oai-udr ... done
Creating oai-udm ... done
Creating oai-ext-dn ... done
Creating oai-ausf ... done
Creating oai-amf ... done
Creating oai-smf ... done注意：由于基站和核心网分别部署在两台不同设备上，我们需要添加路由转发规则。
查阅docker-compose-basic-vpp-nrf.yaml文件可知：
networks:
public_net:
driver: bridge
name: demo-oai-public-net
ipam:
config:
- subnet: 192.168.70.0/24
driver_opts:
com.docker.network.bridge.name: "demo-oai"
public_net_access:
name: oai-public-access
ipam:
config:
- subnet: 192.168.72.0/24
driver_opts:
com.docker.network.bridge.name: "cn5g-access"
public_net_core:
name: oai-public-core
ipam:
config:
- subnet: 192.168.73.0/24
driver_opts:
com.docker.network.bridge.name: "cn5g-core"
我们需要添加的路由就是通向demo-oai-public-net的路由，其ip地址为192.168.70.0/24
2. 路由规则添加
2.1 docker-compose-host配置
- 如果机器未配置数据包转发，则可以使用以下命令完成（重要步骤）
(docker-compose-host)$ sudo sysctl net.ipv4.conf.all.forwarding=1
(docker-compose-host)$ sudo iptables -P FORWARD ACCEPT
2.2 ueransim-host配置
$ sudo ip route add 192.168.70.0/24 \
via IP_ADDR_NIC1\
dev NIC1_NAME
假设ueransim连接的物理接口是ens33(NIC1_NAME)，并且此接口的 IP 地址IP_ADDR_NIC1为192.168.12.33
那么我们添加的路由信息如下：
2.3 ping测试
我们ping demo-oai-public-net的ip即可
(ueransim-host)$ ping 192.168.70.1附录
