Abstract: In one example, a method includes performing L2 learning of a C-MAC address included in a first L2 data message by a first provider edge (PE) router included in an Ethernet Segment of a Provider-Backbone Bridging Ethernet Virtual Private Network (PBB-EVPN); sending to a second PE router within the Ethernet Segment an L2 control message comprising the C-MAC address and a B-MAC address corresponding to the Ethernet Segment of the PBB-EVPN, wherein the L2 control message informs the second PE router of the reachability of the C-MAC address through the first PE router; receiving, by the first PE router and from the second PE router, a second L2 data message as unicast traffic destined for the C-MAC address; and forwarding the second L2 data message to the first CE router.

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: In one example, a method includes configuring a first provider edge (PE) router of a Provider Backbone Bridging (PBB) Ethernet Virtual Private Network (EVPN) to join an Ethernet Segment in active-active mode with at least a second PE router that is operating as a designated forwarder for the Ethernet Segment; receiving, by the first PE router from a remote PE router and prior to the first PE router performing Media Access Control (MAC) learning of a customer-MAC (C-MAC) address that is reachable via a backbone-MAC (B-MAC) address associated with the Ethernet Segment, a network packet that includes the C-MAC address; and in response to determining that the C-MAC address has not been learned by the first PE router and the B-MAC address included in the network packet is associated with the Ethernet Segment, forwarding, by the first PE router, the network packet to a destination identified by the C-MAC address.

Abstract: In general, this disclosure describes techniques for a containerized router operating within a cloud native orchestration framework. In an example, a computing device comprises processing circuitry; a containerized set of workloads; a containerized routing protocol process configured to execute on the processing circuitry and configured to receive routing information; a kernel network stack executing on the processing circuitry and configured to forward packets based on first routing information from the containerized routing protocol process; and a data plane development kit (DPDK)-based virtual router executing on processing circuitry and configured to forward traffic to and from the workloads based on second routing information from the containerized routing protocol process.

Abstract: In general, techniques are described for reporting dynamic tunnels to a path computation element (PCE) of a network to inform path computation by the PCE for traffic engineering within the network. In some examples, a method comprises generating, by a network device configured to route network packets within a network, a dynamic tunnel report message that includes dynamic tunnel description data for a dynamic tunnel that transports the network packets through the network, wherein the network packets transported by the dynamic tunnel each comprises an outer header that does not include a multiprotocol label switching (MPLS) transport label; and sending, by the network device, the dynamic tunnel report message to a path computation element (PCE) for a path computation domain to report the dynamic tunnel to the PCE for inclusion in path computation by the PCE for label switched paths of the network.
