    摘要： In general, the disclosure describes techniques for communicating multicast group leave requests between two or more load-balanced, multi-homed PE routers included in an Ethernet Virtual Private Network (EVPN). The techniques of the disclosure enable the two or more PE routers to synchronize IGMP state and routing information amongst one another to ensure that the one of the multi-homed PE routers elected as the designated forwarder (DF) ceases forwarding the multicast group traffic to the CE router, even if it is not the PE router that receives the IGMP leave request.

    摘要翻译： 通常，本公开描述了用于在包括在以太网虚拟专用网络（EVPN）中的两个或更多个负载平衡的多宿主PE路由器之间传递多播群组离开请求的技术。 本公开的技术使两个或更多个PE路由器能够使IGMP状态和路由信息彼此同步，以确保选择为指定转发器（DF）的多宿主PE路由器之一停止将多播组业务转发到 CE路由器，即使它不是收到IGMP离开请求的PE路由器。

    摘要： In some examples, a computing device comprises a first service function instance to apply a service function and a service function forwarder to: receive a first layer 3 routing protocol route advertisement that includes service function instance data for a second service function instance, the service function instance data indicating a service function type and a service identifier for the service function instance; receive a second layer 3 routing protocol route advertisement that includes service function chain data for a service function chain, the service function chain data indicating a service path identifier and one or more service function items; and send, to the second service function instance and based at least on determining a service function item of the one or more service function items indicates the second service function instance, a packet classified to the service function chain.
