General Routing

  • When DHCP trace options are enabled, there is a possibility that jdhcpd could generate a core file. In general, traceoptions should be enabled only for debugging. They should be disabled once debugging is done.PR1771121

  • Multicast packet duplication occurs under the condition that an ELAN + MVPN network is configured and RP is outside of the core network. In this scenario, egress PE that's non-DF returns multicast traffic to the core side, causing duplication.PR1820746

  • After multiple switchovers broadsync_lock_failure alarms are observed on the Junos OS Evolved ACX7348 platform with the PTP (Precision Time Protocol) configured.PR1826828

  • On all ACX Series platforms, all the traffic directed toward an SRv6 (Segment Routing IPv6) dynamic tunnel isn't forwarded inside the tunnel and is dropped.PR1836457

  • On Junos Evolved ACX7100-32C, ACX7332, ACX7348 platforms having ip-demux lite subscriber configured, it is observed that show subscribers interfaces logical ifl-name detaildoes not display any traffic statistics for ip demux lite subscribers. This is just a display issue and there is no traffic impact due to this issue.PR1850651

  • Storm Control doesn't function when users configure it on an aggregated Ethernet (AE) interface.PR1852048

  • ACX7000 line of Cloud Metro Routers reports an info-level log from evo-pfemand tied to remove EcmpNhInHw textw.PR1866442

  • On Junos Evolved ACX7024 and ACX7024X, the Active Disk Usage Exceeded alarm is raised and not cleared even if the usage is less than 50%. This issue has no impact on traffic. PR1884419

  • Under certain conditions, the DHCP registration to the IFL/IFD event fails, and JDHCPD doesn't receive IFL/IFD events. These conditions cause DHCP packets to fail to route to the kernel, resulting in DHCP packet drops. Restarting the DHCP process resolves the issue. Use the CLI command: restart jdhcpd text.PR1884983

  • This issue is likely to occur when interfaces are activated, deactivated, created, or deleted. Possible causes for this issue include:

    • A bulk change in interface configuration.

    • An administrator-initiated application restart with the request system application node re0 restart app application command.

    • A system-triggered automatic application restart because of internal events.

    PR1885455

Interfaces and Chassis

  • If faulty optics or multiple logical interface units are configured, and interfaces flap, the show interfaces command might not function. PR1867451

  • Whenever the USB device brand Rally2 is connected to USB port A, a stale /dev/sda entry is being created, which results in junk characters being printed in theshow chassis hardware output. To address this issue a fix has been added to verify whether the opened device is a valid block device. If it's not, the code now skips to the next iteration without processing it. Added logic to sanitize the device string by replacing junk characters with spaces. Introduced additional checks to validate block count and size, preventing further processing of dummy or invalid devices. PR1890751

Routing Protocols

  • The RPD process crashes on Junos OS Evolved platforms in a highly scaled scenario of more than 2000 BGP peers if the BGP sessions are un-configured/brought down abruptly. This leads to loss of routing information and leads to loss of protocol traffic.PR1756603

Services Applications

  • When a device is rebooted with PAA installed in 25.2R1 , PAA installation on reboot might fail due to Not found default vrf error. This can be resolved by deactivating and activating or freshly installing the PAA configuration. PR1886928
