General Routing

On rebooting Data Center Interconnect (DCI) Gateway device, while the device is coming up, multicast traffic drop is observed in the highly scaled config. The traffic drop is observed in the following condition. The rebooted device was the EVPN DF on I-ESI and after coming up, the DF election is triggered and the device is elected as EVPN DF on I-ESI. After coming up and elected as DF, the device builds the multicast routes afresh. This results in traffic drop.PR1872219
On QFX10K8/16 , IFL memory is not freed on non-local interface of FPC during configuration changes (eg: IFL delete/deactivate) for L3IFL/L2IFL on AE/Scalar interfaces. Fix is present in common code and risky. It is a day one issue and the per IFL leak is minimal (0.00016% of total Kernel heap size) .PR1884163

On QFX3500 or QFX5100 switches, when parity errors occur on interfaces, they might affect the memory management unit ( MMU ) memories. MMU counters can be corrupted, the interface buffers might be stuck, and there might be interface flaps and traffic loss on the affected ports. As a workaround (restoration only), reboot the system.
