25.2R1-S1-EVO - List of Fixed issues 

PR NumberSynopsisCategory: Border Gateway Protocol
1887911
Major		The rpd process crashes after BGP configuration commits involving group-split-size and RIB-sharding
Product-Group=evo
Severity=Major		On Junos and Junos OS Evolved platforms, configuring "group-split-size" with BGP RIB-sharding(Border Gateway Protocol Routing Information Base Sharding) can lead to a crash in the routing protocol daemon (rpd) when a route update for a non-negotiated NLRI(Network Layer Reachability Information) is received in the update thread. This occurs if the NLRI is targeted at other BGP peers within the group that have negotiated it.
1889749
Major		BGP Prefix-SID Label collision causing RPD crash
Product-Group=evo
Severity=Major		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		The 'bbe-smgd' process crashes in BNG with APM environment when loopback interface is moved/removed from a routing-instance through cli
Product-Group=evo
Severity=Major		On Junos MX platforms which supports 'subscriber-management', in a BNG (Broadband Network Gateway) with APM (Address Pool Manager) address allocation environment having "domain-profile" configuration with "dhcp-gateway-address-last-octet" knob enabled, when a loopback interface is moved/removed from a routing-instance through cli, "bbe-smgd" crash can be observed. The existing traffic is unaffected due to this issue, however, new subscriber logins and logout will be impacted if "bbe-smgd" is not running.

Major		ECN CE bit is not set in an EVPN-VxLAN scenario
Product-Group=evo
Severity=Major		On QFX5130/QFX5700 platforms, in Ethernet VPN-Virtual Extensible LAN (EVPN-VxLAN) scenario, the Explicit Congestion Notification (ECN) Congestion Experienced (CE) bit will not be set for ECN-capable traffic when there is congestion. Since the CE bit is not set, packets will be dropped.

Major		Commit can fail if apply-path contains pattern-matching tokens other than the wildcard <*>
Product-Group=evo
Severity=Major		When the apply-path contains pattern-matching tokens other than the wildcard <*>, prefix list validation may fail, causing the commit to fail.
1891684
Major		Firewall filter IP precedence matches incorrectly when a range of values is configured
Product-Group=evo
Severity=Major		Firewall filter IP precedence match incorrect when a range of values is configured. With matching only one precedence value, either (6 or 7) as an example, packets match the correct term and the action is achieved. Or when configuring a firewall family filter to match the precedence value, for example, of internet-control (6) and net-control (7) in the same term, packets do not match the correct term, and the action is not achieved.

Major		application rpd-agent may restart with a coredump after interface related event changes.
Product-Group=evo
Severity=Major		The rpd-agen application may restart either immediately or latently - after interface are activate, deactivated, created, or removed.via.
PR NumberSynopsisCategory: mgd, ddl, odl infra issues
1884781
Major		Slow configuration commit observed on devices with a single Routing Engine (RE)
Product-Group=evo
Severity=Major		On all Junos OS Evolved platforms with single RE and the system type is cluster, a commit delay is observed when operating with a single RE. This occurs because the system attempts to synchronize with the second RE by default, but since it's not present, the process waits and causes the delay in commit.
PR NumberSynopsisCategory: EVPN control plane issues
1889092
Major		The rpd EVPN module sends a redundant license message to the license infrastructure
Product-Group=evo
Severity=Major		On Junos platforms, when loading the baseline configuration or during BGP flaps or Routing Instance deactivation, and a large number of Group-Based Policy (GBP) tagged routes are removed, a redundant GBP license update message is sent to the license infrastructure for every route deletion. This issue has no impact on traffic.

1848993
Major		The data plane will be out of sync when migrating to EVPN A/A stitching with Vanila VXLAN (PIM Multicast)
Product-Group=evo
Severity=Major		On MX platforms, to improve the convergence of node failures in EVPN MH interconnects with Data Plane VXLAN, migrating to an Active-Active setup may cause the data plane to become out of sync for ARP entries. The gateway learns the MAC address and advertises it to the peer gateway. However, on the peer gateway, some MAC-IP entries may remain stuck in the 'Unresolved' (Ur) state.

Major		In scale EVPN scenario with IRB, host traffic via IRB will be impacted ICMP, OSPF, BGP and L3 protocols on Junos Evolved OS PTX series platform
Product-Group=evo
Severity=Major		On Junos OS Evolved PTX series platforms, in a scale EVPN (Ethernet Virtual Private Network) scenario with IRB (Integrated Routing and Bridging), the traffic via IRB will be impacted ICMP, OSPF, BGP and L3 protocols.

Major		Loss of synchronization are observed when SyncE/PTP configurations are changed
Product-Group=evo
Severity=Major		On MX10004 and MX10008 platforms with JNP10K-RE3 and LC480 line cards, when the device is set up with G8275.1 PTP( Precision time protocol) profile or SyncE (Synchronous Ethernet ) and GRES, performing a GRES switchover causes DPLL-2 to go from "lock" to "unlock." This can lead to a loss of synchronization which can disrupt timing-sensitive services like PTP and SyncE.

Minor		On MPC11E linecards, Periodic error messages are logged as "Temp sensor DDR4 A failed"
Product-Group=evo
Severity=Minor		DDR temp sensor is designed to be used periodically to get temps to send to chassisd. The temp sensors reside may have an intermittent contention that can cause these read failures resulting in DDR4 Temp Sensor Fail" logs on MPC11E linecards.

Major		on QFX5130, duplicate-mac-detect action discard does not work . The action shutdown port should be used instead.
Product-Group=evo		When duplicate-mac-detect feature is configured, if the mac moves from leaf to network in a VXLAN enviroment, the action discard does not take effect. The mac move is prevented. As an alternate, use the action shutdown port instead which is also one of the supported options.

Major		Gamora: RLI 60095: PTP lock status moving from INITIALIZING to PHASE ALIGNED
Product-Group=evo		With T-GM(Timing - Grand Master) enabled system like ACX7024, ACX7348 and ACX7332, when master port link comes up late, then PTP system servo state can move from INITIALIZING to PHASE ALIGNED. This will not cause any issue since when in INITIALIZING state, no PTP packets are sent to down streams devices and in PHASE ALIGNED state, PTP packets are sent with all correct clock parameters. When system moves to directly PHASE_ALIGNED, it is assured that the system is internally locked to phase and frequency of GNSS.

Product-Group=evo		"show host" is not properly XMLized. So from a netconf channel the XML output is encapsulated in an tag. If any automation tool plans to use the XML output of this CLI command, it may have to do some logic on its side (as the response is not 100% XMLized)
