25.2R2-S1-EVO - List of Fixed issues

PR NumberSynopsisCategory: "agentd" software daemon
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.

Major		JDI-RCT:M/Mx: : NGMVPN multicast traffic gets dropped post Change route-distinguisher/route-target on L3VPN instances.
Product-Group=evo
Severity=Major		Not consistent issue and happens when RD and RT change is done in all routing instances while the traffic is running. Also sometimes issue seen only in certain instances. When issue happens there will be traffic drop for inclusive tunnel and affecting all flows on inclusive tunnel and it may not recover unless some external events like route change occurs.
1935730
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)
PR NumberSynopsisCategory: Track PRs in BGP Flow Spec area & is part of BGP inside RPD.
1945627
Minor		BGP IPv6 Flow Specification Session Flapping When inet6-flow Is Enabled
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.

Product-Group=evo
Severity=Major		On all PTX Evolved platforms that support EVPN-VXLAN (Ethernet VPN-Virtual Extensible LAN), when the PTX router acts as a MAC-VRF (Media Access Control - Virtual Routing and Forwarding) EVPN gateway, it will fail to forward traffic routed through the 'irb' interface due to packets being discarded at PFE (packet forwarding Engine), causing packet loss.

Major		Traffic loss observed when restart routing is performed on L3VPN BGP-LU setup
Product-Group=evo
Severity=Major		On PTX10001-36MR, PTX10008 and PTX10016 Junos platforms, when preserve-nexthop-hierarchy is configured and restart routing is performed, then ipv4/ipv6 Layer 3 Virtual Private Network(l3vpn) traffic going over Border Gateway Protocol (BGP)-Labelled Unicast (LU) path may get dropped on downstream routers due to next hop not getting updated properly.

Product-Group=evo
Severity=Major		On Junos OS Evolved PTX10002-36QDD, PTX10004 and PTX10008 platforms with LC1301 line cards, when a device restart is performed while one or more PFE (Packet Forwarding Engine) instances are in a faulty state, the faulty PFE state causes memory corruption post restart. This results in the evo-aftmand process crash and disruption of traffic forwarding.

Product-Group=evo
Severity=Major		On Junos OS Evolved PTX10002-36QDD and PTX10004, PTX10008 platforms with LC1301 line card, when the FPC(Flexible PIC Concentrator) is restarted in high-scale environment, the evo-aftmand process crashes and generates a crash file due to missing validation checks for invalid forwarding next-hop information after restart. This leads to traffic disruption.
PR NumberSynopsisCategory: QFX Control Plane VXLAN
1921796
Minor		Traffic dropped after priority change in VRRP with EVPN-VxLAN scenario
Product-Group=evo
Severity=Minor		On all Junos and Junos Evolved platforms, in Virtual Router Redundancy Protocol (VRRP) with Ethernet Virtual Private Network - Virtual Extensible Local Area Network (EVPN-VXLAN) scenario, when VRRP priority is changed, the VRRP virtual Media Access Control (MAC) address can remain pinned as a static entry on the remote device. As a result, MAC movement does not occur correctly, and VRRP packets are dropped on the leaf device. This impacts VRRP operation after priority changes.

Product-Group=evo
Severity=Major		On all Junos Evolved ACX platforms, underlay traffic is interrupted when ARP(Address Resolution Protocol) request packets required for refresh are dropped due to congestion or ratelimiting conditions. As a result, the nexthop entry temporarily transitions to a HOLD state in hardware even though ARP later recovers in the control plane. Traffic resumes only after the forwarding state is refreshed.

Product-Group=evo
Severity=Minor		On Junos OS Evolved platforms, commit operations with ~38005000 lo0 filter binds take ~4m42s (vs <1m expected). If commit exceeds 5 minutes, mgd times out, which cause configuration load failure and service impact.

Major		The LDP session does not come up when an IPsec SA is configured under OSPFv3
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.

Major		ARP resolution failure for /32 static host routes via IRB in EVPN virtual-switch routing instances
Product-Group=evo
Severity=Major		On all Junos and Junos Evolved platforms that support EVPN (Ethernet VPN) virtual-switch routing instances, ARP (Address Resolution Protocol) resolution fails for static host routes configured with a /32 mask when the next-hop interface is an IRB (Integrated Routing and Bridging) interface and the destination host resides in a different subnet. As a result, ARP entries are not installed, MAC (Media Access Control) addresses of destination hosts are not learned, and traffic destined to those hosts becomes unreachable, causing service impact.

Product-Group=evo
Severity=Minor		On Junos platforms, a race condition occurs when the Simple Network Management Protocol (SNMP) poller attempts to retrieve device license information while subscriber management and SNMP policing features are in use. This condition causes the license-check process to encounter a null pointer and generate a core dump. There is no traffic or service impact. However, license information retrieval through SNMP polling fail until the license-check service recovers.
