    Abstract: The disclosure describes techniques for concurrently operating multiple network stacks, one operating natively and one operating remotely, to control the routing table within a router of a network. An example network device includes a control unit comprising one or more processors. A native routing stack executes on the control unit to exchange routing protocol advertisements with a peer network device in accordance with a routing protocol. The native routing stack is configured to insert first routing entries into a routing table. The first routing entries are based on the routing protocol advertisements. A controller interface executed by the control unit receives second routing entries from a network controller and inserts the second routing entries into the routing table. A routing process generates a forwarding table based on the first and second routing entries.

    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, this disclosure describes techniques for provisioning virtual private network (VPN) services for cloud native routers using a multi-stage process. In an example, a method comprises deploying, in a first computing device, using a layer 2 bridge domain that includes the first computing device, a containerized routing protocol process; deploying, in the first computing device, using the layer 2 bridge domain, a containerized application; configuring, in the containerized routing protocol process executing on the first computing device, a virtual private network (VPN); and exchanging, by the containerized routing protocol process executing on the first computing device, routing protocol messages with another router to provide virtual connectivity between the containerized application and another application that is external to the first computing device.

    Abstract: In general, techniques are described for deploying virtualized cell site routers (vCSRs) capable of layer 2 (L2) forwarding to cell site servers to support management and orchestration of functional units for mobile networks executing on the cell site servers. In an example, a method comprises receiving, at a forwarding plane of a virtualized cell site router (vCSR) of a first Distributed Unit (DU) of a plurality of DU servers of a cell site for a 5G radio access network, the vCSR having a containerized routing protocol process and a forwarding plane configured to perform Layer 2 (L2) switching, L2 packets on a second interface for a second physical link connecting the first DU server to an L2 switch; and switching, by the forwarding plane of the vCSR of the first DU, the L2 packets on a first interface for a first physical link connecting the first DU server to a second DU server of the plurality of DU servers.
