General Routing

  • Once VXLAN is configured on an IFD, its always treated as VXLAN port even though Layer 2 VLAN exists.PR1570689

  • On EX4300-MP platforms, when the command request system software rollback is performed device is going down and dcpfe cores are dumping.PR1631640

  • Unified ISSU on EX4650 switches will not be supported if there is a change in the vendor versions of the chipset SDKs between the releases. This is a product limitation as change in the vendor firmware leads to the chip reset and hence unified ISSU is impacted. The vendor versions in the chipset SDKs should be the same between two Junos OS releases for unified ISSU to work. PR1634695

  • EX4100 48P/T SKUs: On changing interface speed change, the interface statistics are retained on ports 24-to-47 but cleared on ports 0-23. PR1657995

  • Zeroize chooses a fast reboot that minimizes steps/actions and it is considered sufficient if device is in consistent state on completion of zeroize. PR1713678
