Minor		The interface fails to come up after FPC reboot if the streaming server and export profile are not configured correctly
Product-Group=evo
Severity=Minor		On all Junos and Junos evolved platforms with telemetry enabled, if the streaming server and export profile for reporting-rate are not properly configured in the analytics settings, rebooting the FPC would prevent any of the interfaces from coming up.
1923848
Major		Junos Evolved platfrom, when gNMI collecting data from "optics/lanediags/lane/ lane_laser_receiver_power_dbm" and "optics/lanediags/lane/ lane_laser_output_power_dbm" are unreadable
Product-Group=evo
Severity=Major		The JavaScript Object Notation (JSON) encoding of leafs of type "ieeefloat32"(https://github.com/openconfig/public/ blob/master/release/models/types/openconfig-types.yang#L127) is not correct, causing gRPC Network Management Interface (gNMI) data outputs unreadable.
1929823
Major		The sysd process crashes with error logs upon exceeding its memory limit
Product-Group=evo
Severity=Major		On Junos OS Evolved platforms with telemetry streaming configured, the sysd (System Daemon) process crashes on the backup RE (Routing Engine), and error logs are observed when sysd memory usage continues to grow over time, and the memory limit is exceeded. This issue is observed when the 64-bit sysd consumes more memory than the configured system limit when the device has been running for a long time (typically more than 100 days) in the dual RE scenario.

Critical		BGP Prefix-SID Label collision causing RPD crash
Product-Group=evo
Severity=Critical		On all Junos and Junos OS Evolved platforms, In Segment Routing the RPD ( Routing Protocol Daemon ) crash was observed due to different prefixes were trying to use same label, when Bgp prefix SID ( Segment Identifier ) feature was configured and labels were derived using the SID index.

Major		BGP session teardown due to incorrect 'prefix-limit maximum exceeded' error when RIB sharding is enabled
Product-Group=evo
Severity=Major		On all Junos and Junos OS Evolved platforms, when prefix-limit or accepted-prefix-limit is configured under family route-target with rib-sharding, prefix-limit will be incorrectly reported as 'prefix-limit maximum is exceeded'. This causes the BGP session to go down immediately. This occurs because the system incorrectly counts each received route multiple times (once for the main thread and once for each shard)

Product-Group=evo
Severity=Minor		In certain Junos OS releases, BGP sessions may repeatedly reset when IPv6 Flow Specification (inet6-flow) is enabled. This behavior occurs when the router receives specific IPv6 Flow Specification updates that include a default (wildcard) match. Earlier releases do not exhibit this behavior, leading to a difference in observed stability when upgrading.

Minor		10G channelized interface fails to reach full line rate due to low-rate queue overscheduling
Product-Group=evo
Severity=Minor		On Junos OS Evolved PTX10004, PTX10008 and PTX10016 platforms using LC1201 or LC1202 line cards, a 10G channelized interface created from a 100G or 400G port may fail to reach full line rate. This issue occurs because the interface cannot fully utilize the link due to scheduler behavior when the interface has more than 4 channels and one or more output queues are set to a 5% or lower rate limit and receive a very high offered load compared to other queues.

Major		Commit error when deleting interface with hierarchical scheduler enabled
Product-Group=evo
Severity=Major		On ACX7100 and ACX7348 platforms running Junos EVO 24.4R1, a commit error may occur when attempting to delete an interface (IFD) that has the hierarchical scheduler enabled and configured. The hierarchical scheduler is a required dependency for the output traffic control profile applied on interface sets (IFLSET). During commit validation, this dependency is enforced, preventing interface deletion until associated hierarchical scheduler configurations are deactivated.

Major		L3VPN traffic drop due to incorrect destination MAC after MAC move in core
Product-Group=evo
Severity=Major		On all Junos OS Evolved ACK7K platforms, When a Media Access Control (MAC) address change or move occurs on the core side of the ingress Provider Edge (PE) node in a Layer 3 Virtual Private Network (L3VPN) topology, the ingress PE correctly updates the unicast Internet Protocol version 4 (IPv4) next-hop via Address Resolution Protocol (ARP); however, the dependent IPv4 to Multiprotocol Label Switching (MPLS) (indirect) L3VPN next-hop fails to update its destination MAC address. As a result, L3VPN MPLS traffic is forwarded with a stale destination MAC address, leading to incorrect packet forwarding and service impact.

Product-Group=evo
Severity=Major		On Junos Evolved platforms, when Open Shortest Path First version 3 (OSPFv3) Internet Protocol Security (IPsec) SA is applied at the interface (IFD/IFL) level, Label Distribution Protocol (LDP) is able to discover the neighbor via User Datagram Protocol (UDP) Hellos, but fails to bring up the Transmission Control Protocol (TCP) session, preventing the LDP session from becoming operational. Disabling the OSPFv3 IPsec SA immediately restores normal LDP operation. During the service impact, the session will be down and traffic will not be send. Once the LDP session comes up, traffic can be routed through it.
