What’s Changed in Release 21.4R1


  • Output for show Ethernet switching flood extensive—The output for show ethernet-switching flood extensive now displays the correct next-hop type for Virtual Ethernet and WAN mesh group in an EVPN-VXLAN network as unilist. Previously, the output for show ethernet-switching flood extensive would misidentify the next-hop type as composite.

General Routing

  • Juniper Agile Licensing (EX2300-VC, EX3400-VC, EX4300-VC, EX4400-24MP, EX4400-48MP, PTX10003, PTX10016, QFX5130-32CD, QFX5110-32Q, QFX5110-48S, QFX5120-48T, QFX5210-64C, QFX5200, and QFX5220)—Starting from this release onwards, the Juniper Agile License Manager is deprecated. You can use the Juniper Agile Licensing Portal to activate, install, manage, and monitor licenses on Juniper Networks devices.

Interfaces and Chassis

  • When configuring multiple flexible tunnel interface (FTI) tunnels, the source and destination address pair needs to be unique only among the FTI tunnels of the same tunnel encapsulation type. Prior to this PR, the source and destination address pair had to be unique among all the FTI tunnels regardless of the tunnel encapsulation type.

Network Management and Monitoring

  • The configuration accepts only defined identity values for nodes of type identityref in YANG data models (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—If you configure a statement that has type identityref in the corresponding YANG data model, the device accepts only defined identity values (as defined by an identity statement) as valid input. In earlier releases, the device also accepts values that are not defined identity values.
