Abstract: In one implementation, sub-interfaces are defined in Layer three (L3) tunnels, such as generic routing encapsulization (GRE) or Internet protocol security (IPsec) tunnels. Sub-interfaces inside a L3 tunnel may be preferred to using several L3 tunnels. The flow label of the tunnel header is used to define sub-interfaces of a tunnel interface. The flow label is populated with a routing instance identifier to index the sub-interfaces.

Abstract translation: 在一个实现中，子接口在三层（L3）隧道中定义，例如通用路由封装（GRE）或因特网协议安全（IPsec）隧道。 L3隧道内的子接口可能优于使用多个L3隧道。 隧道头的流标签用于定义隧道接口的子接口。 流标签用路由实例标识符填充以对子接口进行索引。
