General Routing

  • In VPLS MH cases, the standby UNI ifl in backup router will be programmed in disable state, by adding the UNI interface to invalid vpn id in HW. During switch over the UNI ifl will be deleted and will be added under the VPLS instance VPN id. In issue case, UNI interface added under invalid VPN id in backup router is tried to deleted by passing the VPLS instance vpn id, causing the issue. This issue is applicable only for ACX5k series.PR1665178

  • On ACX1K/2K platforms, when a lo0.x filter is configured under a vrf type routing-instance, any IPv4 transit traffic that makes ARP request to generate to the CE-facing interfaces will fail in ARP resolution due to the ARP request packets are discard by lo0.x filter if no specific term to accept the IPv4 packets. PR1737999

  • On Junos ACX2200, the PTP(Precision Time Protocol) packets are not processed over GE (Gigabit Ethernet) interfaces after a reboot due to error in initialisation sequence of PTP. This impacts all functionalities associated with PTP as PTP packets are dropped.PR1755852

  • Some Junos OS Releases from 21.4R3 to 22.4R3, might display the Remote fault state as 'Offline' in show interface by default. PR1764243

  • On Junos ACX5448 device with SFP-T optics, speed displays wrong in CLI when executing show interface interface-name CLI command will display "Unspecified" speed. Speed value will not be updated properly. There is no traffic impact.PR1764303

  • When restart chassis-control trigged on M/MX router has config with ccc instance, syslog is error out " Err] ACX_ASIC_PROGRAMMING_ERROR: pfe_dnx_translation_set: Error, bcm_vlan_port_translation_set rv:Entry not found ".PR1764966

  • On ACX5048/ACX5096 platform, after the device is upgraded, disabling an interface and then rebooting the device will cause a critical issue. All interfaces will go down, resulting in a complete traffic drop. There is no known workaround to prevent this service interruption during the upgrade process.PR1786687

  • ACX1100 PTP(enterprise profile) is stuck at freerun state after upgrading junos to 21.2R3PR1789694

  • ACX710 does not recognize GPON OLT 740-124448 reports NON-JNPR after ACX power cycle. The same error state NON-JNPR can be observed when GPON OLT SFP is installed into ACX router.PR1801112

  • Multicast route is reset every 5 mins with igmp receiver on acx2200 with small traffic loss. Multicast route that are not active would get reset after 5 minutes due to cahce timeout. This was happening even for active routes that had traffic.PR1805017

MPLS

  • The default behavior of local reversion has changed from Junos OS Release 16.1 and that impacts the LSPs for which the ingress does not perform make-before-break. Junos OS does not perform make-before-break for no-cspf LSPs. PR1401800
