New Features in Juniper Cloud-Native Router Release 23.1

  • Support for native VLAN—Juniper Cloud-Native Router now supports receiving and forwarding bridged Ethernet frames with 802.1Q VLAN tags. Typically, trunk ports accept only tagged packets, and the untagged packets are dropped. You can enable a JCNR fabric trunk port to accept untagged packets by configuring a native VLAN identifier (ID) on the interface on which you want the untagged packets to be received. When a JCNR fabric trunk port is enabled to accept untagged packets, such packets are forwarded with the native VLAN ID applied to them.

  • Support for preventing local switching—Juniper Cloud-Native Router now provides support to prevent interfaces in a bridge domain that are a part of the same VLAN group, from transmitting ethernet frame copies in between those interfaces. The noLocalSwitching: key provides the option to enable the functionality on the selected VLAN IDs.

    Note:

    The noLocalSwitching: functionality is a Technology Preview feature in the Juniper Cloud-Native Router Release 23.1.
