    Abstract: Techniques are described to provide layer 2 (L2) circuit failover in the event connectivity to an Ethernet Virtual Private Network (EVPN) instance is lost. For example, if one of multi-homed provider edge (PE) devices loses connectivity to the EVPN instance, the PE device may mark its customer-facing interface as down and propagate the interface status to the access node such that the access node may update its routing information to switch L2 circuits to another one of the multi-homed PE devices having reachability to the EVPN instance. In some examples, the plurality of PE devices may further implement Connectivity Fault Management (CFM) techniques to propagate the interface status to the access node such that the access node may update its forwarding information to send traffic on a different L2 circuit to another one of the multi-homed PE devices having reachability to the EVPN instance.

    Abstract: A network device operable as a provide edge router is described. The network device comprises one or more processors operably coupled to a memory; a configuration interface configured for execution by the one or more processors to receive configuration data configuring the network device as a provider edge router of an intermediate layer 3 network to provide multi-homed layer 2 virtual bridge connectivity to a customer edge device using an active-standby mode of operation; and a routing process configured for execution by the one or more processors to send, to a remote provider edge router in response to determining the network device is able to send layer 2 packets to the customer edge device, a route advertisement that includes a static route specifying a layer 3 address of the customer edge device as a next-hop for a layer 3 subnet.

    Abstract: An example router includes a control unit configured to receive virtual private network (VPN) routing and forwarding table (VRF) configuration data defining a VRF for a VPN and VPN address space for the VPN, receive configuration data defining a measurement endpoint for measuring performance of a layer 3 (L3) service and associating the measurement endpoint with a remote measurement endpoint of a remote router. The control unit is configured to encapsulate, to generate a flow measurement packet, a layer 2 (L2) measurement packet in a layer 4 (L4) header and an L3 header, where the L3 header includes a source L3 address within the VPN address space and associated with the measurement endpoint, and where the L3 header includes a destination L3 address within the VPN address space and associated with the remote measurement endpoint. The control unit is configured to output the flow measurement packet to the remote router.
