What’s Changed in Release 22.2R1

General Routing

  • Instance type change is not permitted from default to L3VRF in open configuration (ACX Series and QFX Series)—DEFAULT_INSTANCE is the primary instance that runs when there is no specific instance type configured in the route set routing-options?. Any instance you explicitly configure is translated into set routing-instance r1 routing-options?. The issue appears in translation, when you change instance type DEFAULT_INSTANCE (any instance to DEFAULT_INSTANCE) to L3VRF or L3VRF to DEFAULT_INSTANCE. As a result, such changes are not permitted. Additionally, DEFAULT_INSTANCE can only be named DEFAULT, and DEFAULT is reserved for DEFAULT_INSTANCE, therefore allowing no such changes.


  • OpenConfig container names for Point-to-Multipoint per interface ingress and egress sensors are modified for consistency from "signalling" to "signaling".

Network Management and Monitoring

  • Changes to the NETCONF <edit-config> RPC response (ACX Series, PTX Series, and QFX Series)—When the <edit-config> operation returns an error, the NETCONF server does not emit a <load-error-count> element in the RPC response. In earlier releases, the <edit-config> RPC response includes the <load-error-count> element when the operation fails.

Routing Protocols

  • SSH TCP forwarding disabled by default—We've disabled the SSH TCP forwarding feature by default to enhance security. To enable the SSH TCP forwarding feature, you can configure the allow-tcp-forwarding statement at the [edit system services ssh] hierarchy level.

    In addition, we've deprecated the tcp-forwarding and no-tcp-forwarding statements at the [edit system services ssh] hierarchy level.

User Interface and Configuration

  • When you configure max-cli-sessions at the edit system hierarchy level, it restricts the maximum number of cli sessions that can coexist at any time. Once the max-cli-sessions number is reached, new CLI access is denied. The users who are configured to get the CLI upon login, are also denied new login.
