General Routing

  • On QFX5220-32CD, VLANs between 3968 and 4095 are reserved for Layer 3 interfaces by default. So, these VLANs cannot be used for Layer 2 interfaces. As of now there is no commit check added for this purpose. You need to take care of this while configuring VLANs for Layer 2. PR1423468

  • On the QFX5130-32CD platform running Junos OS Evolved, you cannot clear or reset the disk option specified in the scheduled request node reboot command. The node reboots with the disk option last specified. PR1517596

  • FIPS mode is not supported. PR1530951

  • On all QFX Junos OS Evolved platforms, if scaled OSPF (Open Shortest Path First) neighbors (e.g 512 neighbors) are formed over an IRB (Integrated Routing and Bridging) interfaces with Layer 2 interfaces in the interface-mode trunk, the OSPF routes might be not learned from the neighbors. The issue results in traffic loss. PR1570498

  • On QFX5700, Autoneg is not supported for 100G DAC interfaces. PR1594135
