General Routing

  • During boot up PTP FPGA link resets which toggles the link, Hence the message observed in the console. PR1572061

  • Whenever interface deactivate HW counters for SR-TE path related get deleted, re-adding these path on enabling the interface can cause loss of counter. Same behavior is there while deleting one of the SR-TE paths in a given SR-TE policy. PR1630517

  • Supported matches (fltTypes) work only for one filter. One might not select and combine them across two different filters.PR1674004

  • In Junos OS Evolved, when any configuration is committed and commit complete is seen on the CLI, the system operational state takes a little extra time to reflect the committed configuration. This extra time is taken by Junos OS Evolved configd daemon to process the commit. The extra time taken is proportional to the size of the committed configuration. In the PR scenario, the Routing Engine switchover is triggered immediately after the commit complete. The immediate Routing Engine switchover interrupts the commit processing, which is still under progress by configd to publish the objects to Junos OS Evolved DDS (Distributed Data Store). This results in an inconsistent Junos OS Evolved operational state which is out-of-sync with the committed configuration. PR1680192

  • While config commit going through, if switchover happens, both RES are out of sync. PR1680223

Network Management and Monitoring

  • Junos OS Evolved has a feature to block or deny all hidden commands. Users can get this feature by configuring set system no-hidden-commands. However when this is configured and committed Junos OS blocks or denies new netconf or junoscript XML sessions. As a workaround users can delete system no-hidden-commands configuration statement and start new netconf or junoscript sessions. PR1590350

Routing Policy and Firewall Filters

  • The IPv4 unsupported filter match fragment-flags reserved must not be used, as it matches don't fragment traffic pattern as well.PR1676517
