General Routing

  • On all Junos OS platforms, agentd process crash will be seen in telemetry streaming longevity test. PR1647568

  • On PTX10002, all odd ports have a WAN re-timer connected to it , which might introduce more time during fault recovery, such as LocalFault clear. Therefore, sometimes even if the fault is of the order of milliseconds, the port might still get hold-time expired and flap when the configured hold-time down less than 3s. The behavior is confirmed as hardware limitation.PR1687092

  • P2MP RSVP Phase 2 MTS : Per Packet Load Balancing is not working as expected in VPTX 5000. PR1712824
