### PCF predefined-sm-policy-rules.xml

配置基于 PCC Rule 的 Traffic Routing（分流）规则。

```xml
# 配置 tcList 与 FlowList 的关系。
<pcc pccRuleId="pcc11_3_1" flowListId="flowList0" precedence="1" qosListId="qosList6" tcListId="tcList11" />

# 配置 Traffic Routing 的目标 DNAI。
<tc tcId="tc11" dnai="89"/>
```

### SMF upf.xml

## 单 UPF 多 DN 精确路由方案

一个 UPF 对应两个 DNN，需要在 UPF 上配置两个 N6，这两个 N6 处于不同的 NWI。以两个物理 N6 为例，也可以换成虚拟的。

NOTE：N6 GTP-U 不需要显示配置。
