General Routing

  • Due to BRCM KBP issue, route lookup might fail. PR1533513

  • On ACX platforms, traffic issue might be observed with downstream devices when Precision Time Protocol(PTP) is configured (G.8275.1 PTP profile) along with PHY timestamping and Multiprotocol Label Switching (MPLS) terminated on 10G interface. The transit PTP ipv4 packets are updated with wrong Correction Factor(CF). This issue could be restored by disabling PHY stamping. However, disabling might impact the PTP performance. PR1612429

  • On ACX5448 devices with VM Host-based platforms, starting with Junos 21.4R1 or later, you need the SSH and root login for copying line card image from Junos VM to Linux host during installation. The SSH and root login are required during installation. Use deny-password instead of deny as default root-login option under the SSh configuration to allow internal trusted communication. PR1629943

  • On ACX5448 devices, Junos OS does not support Hierarchical-scheduler (HQOS) on MPLS (Core facing) interface. Enabling HQOS on MPLS Core facing interface causes unexpected traffic forwrading behavior. PR1630086

  • On ACX5048 and ACX5096 devices, Junos OS does not support interface speed 10m on 1G interface. PR1633226

  • On ACX5448 and ACX710 devices, all types of delegated BFD sessions configured on routing-instance other than the default routing-instance might not come up.PR1633395

  • On ACX710 devices, the rpd process might generate core files. . The rpd process keeps running and there is no functional impact. PR1663050

  • On ACX5000 devices, 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. PR1665178

  • Due to race condition at the time of streaming and simultaneous disconnection of clients, the na-grpcd process might generate core files at rare ocassions. This issue causes temporary outage of streaming telemetry services. The service will self recover upon restart of the process. PR1665516

  • When there are more than 1 DHCP server connected to the device and zeroize in initiated then multiple route are added and the file server is not reachable after the zeroize if it is not reachable through the default route. PR1675011
