Junos Software service Release version 18.4R1-S1 is now available.
Some SFBs might go down when one of the PSMs in the chassis generates a bad output voltage which is out-of-range.
On MX2010/MX2020, some Switch Fabric Boards (SFBs) might go down due to one of the Power Supply Modules (PSMs) in the chassis generates a bad output voltage which is out-of-range.
The best and the second-best routes might have the same weight value if BGP PIC is enabled.
In BGP PIC (Prefix Independent Convergence) scenario, next-hop of unequal BGP multipath routes might have the same weight (0x1), resulting in unexpected load balance for traffic.
Static demux0 logical interfaces do not come up after config change if underlying interface is et.
Static demux0 logical interfaces do not come up after config change if underlying interface is et ( 100 GE ). After config change et interface gets flushed in order to reparse the config. During this DCD miss to create the dependency between demux0 logical interfaces and underlying et interface which results in flushing off the demux0 logical interfaces. This issue will be seen only if underlying interface is et. For all other interfaces this has been already taken care. This is day one issue. Workaround for this problem is Restarting DCD (or the entire RE reboot), clears the problem or else use 'commit full' instead of commit while committing new config.
Transit UDP 500/4500 traffic is not passing across SRX5k when using SPC3
