General Routing

  • Delegated BFD sessions configured on routing-instance might fail to come up. PR1633395

  • ACX-5448: PPS values seen on interface even when it is in disabled state. PR1685344

  • Interface queues display incorrect values of default reserved buffers. PR1689183

  • dc-pfe: HEAP malloc(0) detected! when a VPLS instance is deactivated in ACX5048. PR1692400

  • Traffic loss is more than expected with OSPF TI-LFA node- protection enabled and the primary path is down. PR1695292

  • Traffic drops seen after making COS configuration change on ACX710. PR1704589

  • [interface] [acx_ifd] ACX7100-32C :: Can we unhide set chassis cb since we need customer to set CB temperature thresholds. PR1705035

  • L2VPN traffic is dropped as the default MTU is less by 4 bytes. PR1707932

  • The member interface will not be added to the AE bundle if the link-speed of the AE interface does not match that of the member. PR1713699

  • The traffic through the AE member link will be dropped. PR1714111

  • SFP-T cannot be recognized after detecting an I2C error on ACX5448. PR1715924

  • SNMP MIB OID output showing wrong temperature value if device running under negative temperature. PR1717105

  • L3VPN traffic loss and PFE errors can be seen after an LSP Flap. PR1719507

  • The Forwarding Engine Board (FEB 0) crashes and impacts traffic when the L2circuit IGP primary path port is down. PR1720827

  • The multicast packets could hit the CPU/RE on ACX5448 and ACX710 platforms. PR1722277

  • Intermittent MAC move is observed in VPLS environment when ACX5448 or ACX710 is acting as a PE device. PR1722919

  • Traffic is getting discarded in PFE when forwarding-table is changed. PR1723624

  • Media MTU of ACX5448 will be 4 byte larger for transit packets. PR1724750

  • [ACX5048] L2circuit might drop forwarding traffic after flaps although it's in UP state; acx_rt_ccc_eth_vpws_vpn_uni_port_add:UNI VPWS port_add failed AC-IFL: <> VPN: <>(-15:Invalid configuration). PR1726711

  • A panic reboot will be observed due to deadlock on VMhost platforms. PR1727985

  • Traffic drops on certain ACX platforms after it is upgraded. PR1731081

  • The IPv4 classification and EXP remarking might not work as expected in the IP-MPLS scenario. PR1732509

  • After issuing clear VPLS mac table command preceded with clear MPLS statistics command execution on ACX routers, traffic loss is observed with the failed error message. PR1734600

  • Crash on all Junos VMhost platforms due to deadlock panic. PR1735843

  • Traffic loss in ACX710 and ACX5448 on any-mpls unicast nexthop protocol configuration. PR1742960

  • EVPN routes does not work properly when resolution preserve-nexthop-hierarchy is enabled. PR1746964

  • QSFP interfaces show additional flap during PFE bringup. PR1747140

  • The memory consumption increases due to memory leak. PR1747992

  • Interfaces fail to come online post upgrade. PR1750814

  • The rewrite rule stops working when classifier is attached to wildcard IFL. PR1753411

  • ACX:COS: Default ieee-8021p classifier not working for UNI interface for Layer 2 services. PR1756150

  • Interface flaps leading to PFE crash due to FPC heap corruption. PR1764083

  • Traffic convergence is longer than usual after the CoS rewrite. PR1770491

Interfaces and Chassis

  • On Junos platforms the DCD will flap the IFLs which are part of EVPN routing-instance. PR1712800

  • The interface speed gets set to a lower speed when the interface is disabled and enabled because renegotiation of the interfaces happens at the previously negotiated speed. PR1714267

MPLS

  • The rpd process crash is observed when RSVP LSP at Juniper transit/ingress router receives RESV message with RESVCONF object in multi vendor deployment. PR1723229

Platform and Infrastructure

  • TCP window scaling might be not applied to the first TCP packet sent to the client after the three-way handshake, leading to unnecessary segmentation. PR1761242
