Class of Service

  • The default code-point aliases and respective CoS value Bit patterns are inconsistent with Junos OS. PR1667404


  • Junos OS and Junos OS Evolved: RPD core upon receipt of a specific EVPN route by a BGP route reflector in an EVPN environment (CVE-2022-22219). PR1675054

General Routing

  • The Layer 3 packets with the destination as IPv6 Link Local address will not work. PR1638642

  • HTTP(S) file download hangs over EVPN-ETREE. PR1653531

  • On ACX5448 platform, physical interfaces of FPC remain up even though it lost communication with Routing Engine. PR1659949

  • Packet count might occasionally be 0 for some interfaces in monitor interface traffic. PR1661617

  • The Layer 2 circuit backup might not get reverted to primary in rare condition. PR1661802

  • After activating EVPN-ETREE service on ACX5448 Packet Forwarding Engine might crash. PR1662686

  • The rpd core might be seen when there is a synchronization issue. PR1663050

  • Multicast upstream interface does not change to back up link when PIM neighbor is removed or flapped and causes a traffic impact. PR1663271

  • Transit traffic drop was seen for BGP-LU(Border Gateway Protocol-Labeled Unicast) prefix on ACX5448 or ACX710 when BGP-LU label routes has ECMP(Equal-Cost Multipath) forwarding path. PR1663563

  • Adding an empty interface to an aggregate Ethernet bundle causes traffic drop. PR1663651

  • FXPC core might be observed when deactivating a child memeber link from aggregate Ethernet bundle. PR1665511

  • In the SRTE scenario, sensors are wrongly populated for colored tunnel BSID routes when uncolored tunnels are enabled. PR1665943

  • Inline BFDv6 Sessions might go DOWN and stay in that state on ACX5448 and ACX710 platforms. PR1666746

  • Traffic loss is observed when the VRRP is configured over the aggregate Engine interface. PR1666853

  • On ACX710 and ACX5448 its variants Packet Forwarding Engine might crash due to configuration of BFD. PR1667129

  • Shutting the CE interface and bringing back up causes traffic (going towards the core) drop. PR1667724

  • LLDP neighborship might fail if the chassis-id format of the LLDP packet is xx:xx:xx:XX:XX:xx. PR1669677

  • Chassis alarms for smart errors not set or cleared. PR1669968

  • ACX710 : Log related to resources reported after EVPN RI are deactivated / activated multiple times : ACX_BD_ERR: dnx_bd_alloc_l2_svlan: System reached L3 IFL and BD limit(12286). PR1670683

  • MX-SPC3 PIC core dump is seen when a CPCD service is modified. PR1675990

  • The LLDP packets will not be transmitted over Layer 2 circuit on the ACX platform. PR1678752

  • ACX5448 : RIO DNX PFE wrongly spelled as QUMARN instead of Qumran. PR1682819

  • The traffic drop would be observed with inter-vlan configuration when deactivating and activating the EVPN routing instance. PR1683321

  • On the ACX710 device, the IEEE 802.1p priority and DEI values in the locally generated VLAN-based IP packets might be changed when sourced from the IRB interface. PR1683770

  • ACX5448:ACX710 Layer 2 circuit traffic drop with control-word enabled or control-word configuration change. PR1683900
