New Features

New Features in Juniper Cloud-Native Router Release 22.2

• Juniper Cloud-Native Router Controller (cRPD or JCNR-Controller)–The JCNR-controller is based on our tried-and-tested containerized routing protocol daemon, cRPD. We use cRPD in the cloud-native router to provide the control plane functions and interface with the JCNR-vRouter component. See Juniper Cloud Native Router Controller.

• JCNR-vRouter–JCNR-vRouter is a dataplane development kit (DPDK)-based forwarding plane. JCNR-vRouter is able to provide high-speed L2 forwarding using DPDK and enforce L2 access control lists (ACLs). See JCNR-vRouter.

  JCNR-vrouter uses a component known as the vRouter-agent to receive communication from the cRPD.

  See JCNR-vRouter.

• JCNR-CNI–Juniper Cloud-Native Router uses the container network interface application, JCNR-CNI to provide container network and Kubernetes Pod interfaces. See JCNR-CNI.

• Software Licensing–Juniper Cloud-Native Router release 22.2 introduces the Juniper agile software license model. In the 22.2 Release, we do not enforce license compliance, we only report out-of-compliance status. See Juniper Cloud-Native Router LIcensing

• Configuration by Helm Chart–Juniper Cloud-Native Router supports deployment-time configuration with the use of Helm charts.

  See Juniper Cloud-Native Router Deployment Guide

• NETCONF–You can configure the Juniper Cloud-Native Router control plane using the NETCONF protocol.

• Networking Features

  • L2 Mode DPDK Forwarding Plane–Juniper Cloud-Native Router supports L2 mode in the DPDK forwarding plane for fabric and workload interfaces

  • Ethernet Packet Switching–Juniper Cloud-Native Router operated in L2 mode activates ethernet switching capabilities in the forwarding plane.

  • MAC Address Handling–Juniper Cloud-Native Router Release 22.2 operated in L2 mode allows the forwarding plane to handle MAC addresses without involving the control plane (MAC learning and aging)

  • Bridge Domain Support–Juniper Cloud-Native Router supports bridge domains

  • VLAN Tagging–Juniper Cloud-Native Router supports VLAN tagging on logical interfaces

  • Trunk Port Support–Juniper Cloud-Native Router operated in L2 mode allows for the creation of trunk ports which allow multiple VLANs to transit the port.

• Support for Multiple Interface Types–Juniper Cloud-Native Router operated in L2 mode allows fabric and pod interfaces of the following types:

  • Kernel mode access interfaces that are used to bypass the DPDK forwarding plane in favor of the kernel-based forwarding plane
  • Virtio trunk interfaces that can pass traffic from multiple VLANs
  • Multiple Virtio sub interfaces that can each pass VLAN-tagged traffic
  Juniper Cloud-Native Router Interface Types.

• Fabric Interface Functions Support–Juniper Cloud-Native Router fabric interfaces can be based of Virtual Functions or Physical Functions of a NIC

• IP Address Allocation for Application Pods–Juniper Cloud-Native Router Release 22.2 supports allocation of IP addresses for Kubernetes application pods by the JCNR-CNI.

  See JCNR-CNI.

• L2 Access Control Lists (ACL)–Juniper Cloud-Native Router Release 22.2 running in L2 mode supports the creation and enforcement of L2 access control lists (ACL) based on MAC address or ethertypes

  See L2 ACL

• Traffic Rate Limiting–Juniper Cloud-Native Router Release 22.2 allows for the rate limiting of L2 broadcast and multicast traffic

• NIC Support–Juniper Cloud-Native Router Release 22.2 supports special features such as VLAN offload and Dynamic Device Personalization (DDP) on the following NICs:

  • Intel 810

  See System Resource Requirements

• Event Notification Support–Juniper Cloud-Native Router uses syslog-ng to convert event logs from various Pods and containers into JSON-encoded notifications.

  See Logging and Notifications.

• Automatic Generation of Bridge Domains and JCNR-Controller Configuration–Juniper Cloud-Native Router automatically generates bridge domain and JCNR-Controller configuration during deployment through the use of Helm charts.Juniper Cloud-Native Router Deployment Guide.

• Kubernetes (K8s) Liveness Probes for JCNR-Controller and JCNR-vRouter–Juniper Cloud-Native Router supports Kubernetes liveness probes for JCNR-Controller and JCNR-vRouter containers.

  See Logging and Notifications.
