General Routing

  • The .include directives are deprecated, and support for them is removed in a future version.PR1647592

  • Some VPLS and L2VPN streams are dropped on the aggregated Ethernet interface after a change in MTU configuration on the aggregated Ethernet interface. PR1671451

  • The evo-pfemand core file is observed during the device reboot and interface flaps. PR1677679

  • ACX7100-32C port down when configuring speed as 10g in Junos OS Evolved 22.2R1. PR1681560

  • PTP or TWAMP does not work on PM50 ports ( et-0/0/0 to et-0/0/3 on ACX7024 and all ports on ACX7100-48L) if FEC74 is enabled on that port. PR1684770

  • Traffic egressing out of layer 3 interface is affected when configuration changes are made. PR1687260

  • Traffic failure when you ping from ACX leaf to it's directly attached host.PR1687842

  • jdchpd core file seen with dhcp-snooping persistent configuration. PR1688644

  • Unable to appropriately failover the incoming traffic with multiple links. PR1688773

  • ACX7509 :: timing PTP does not support Routing Engine switchover. PR1690984

  • Inconsistent clear ARP behavior leads to traffic loss to host(s). PR1691524

  • Junos OS Evolved::JDI_REG::ACX7100: DHCPv6 relay bindings are not as expected after deactivating and activating interfaces. PR1692278

  • LACP and LLDP protocol traffic is not transparently forwarded across the CE devices.PR1692402

  • [jdhcpd] multiple DHCP release packets sent to the DHCP server in IRB interface with a virtual gateway address (VGA) with EVPN/MPLS ERB model.PR1693625

  • RPD core file is seen after the switchover. PR1694773

  • System reboot related log message SYSTEM_REBOOT_EVENT might not be displayed in show log messages | match SYSTEM_REBOOT_EVENT. PR1696668

  • On ACX7509, MACsec MKA sessions might not come up after restarting FPC multiple (4-5) times. The only way to recover from this situation is to reboot the chassis.PR1701941

  • On Junos OS Evolved platforms, the traffic impact is seen as the set system process routing enable or set system process routing disable configuration does not work as expected. PR1702734

  • Port-mirroring is not working if hierarchical-scheduler is enabled on the analyzer output port.PR1703567

  • In EVPN-MPLS Mutihoming scenario DF election gets stuck in the preference based state.PR1662954

  • In the EVPN-MPLS multihoming scenario, MAC-IP route deletion and addition result in traffic drop. PR1691132


  • show route forwarding-table destination command takes long time in a scaled system for non-/32 prefixes. PR1685545

Interfaces and Chassis

  • LLDP packet drop is seen when the physical interface (IFD) is configured with flexible-vlan-tagging. PR1689391

Routing Protocols

  • BGP or OSPF neighbors do not come up in Junos OS Evolved platforms if IPSEC security associations are used to authenticate the peer. PR1674802

Services Applications

  • ACX7100: Spikes in jitter that are larger than 5 ms for UDP plugin in PAA for high bandwidth or small packet size. PR1680309

  • Impaired accuracy for delay measurements using PAA. PR1697270

User Interface and Configuration

  • Test configuration might fail even though the configuration file has valid configurations. PR1671112
