摘要
Techniques are disclosed for an Ethernet Virtual Private Network (EVPN) Virtual Private Wire Service (VPWS) network with service interface-aware forwarding. In one example, a first network device signals to a second network device, using EVPN route advertisements, a multi-service service tunnel to transport network packets for a plurality of services. The services are identifiable by virtual local area network (VLAN) identifiers in the packets. The first network device is configured with a single transport interface for the service tunnel and the single transport interface is configured with respective service interfaces for the services. The first network device detects failure of a failed service interface of the service interfaces and outputs, in response to the failure, an EVPN route withdrawal message for the service tunnel that identifies the service corresponding to the failed service interface.
