General Routing

  • In 20.3 Junos OS Evolved, fabsopke-fchip core can be seen if fabsopke-fchip restart and SIB offline happened one after other with in the same minute. Any previous alarm will not get cleared. PR1525577

  • Some of the frequencies shall be failing performance for PTP-PTP and PTP-1PPS. PR1624478

  • On all devices running Junos OS Evolved, where this is a high BGP scale with flapping route and the BGP Monitoring Protocol (BMP) collector and station is very slow, the rpd process might crash due to memory pressure. PR1635143

  • On PTX10003, PTX10003-160C, PTX10003-80C, PTX10008, and PTX10016 Junos OS Evolved platforms, MPLS (Multiprotocol Label Switching) FRR (Fast Reroute) convergence takes longer time when an AE (Aggregate Ethernet) interface is disabled.PR1660701

  • The OpenSSL project has published security advisories for multiple vulnerabilities resolved in OpenSSL. Please Refer to https://kb.juniper.net/JSA70186 for more information.PR1661450

  • Layer 2 related daemons - lacpd, ifmand, and arpd - when patched using JSU may cause the Junos OS Evolved router to not boot up. PR1676132

  • When CFM configurations are present on the router, and the router is rebooted, below error logs might be seen. [Error] CTRL:CFM:: PpmCtrlProtoCfm::getSessionKey: Unknown Cfm transmit session type params0x0 ( ) There is no feature impact when this error log is seen. CFM sessions will be unaffected. The error log is not emitted consistently, and may be seen only sometimes.PR1695518

  • Junos OS and Junos OS Evolved has a limitation of 255 characters for resource names. Increasing the limit will have implications on the CLI output and same changes will needed to be propagated to lower layers where the resources are served from. PR1695980

  • On Junos OS Evolved Platforms, any UI (user interface) set (configuration, script, license) changes done post software addition were being lost after the subsequent reboot.PR1699699

  • On PTX platforms running Junos OS Evolved, modification to a firewall filter configuration can crash the evo-aftmand (Advanced Forwarding Toolkit Manager) process. This results in unexpected behaviour and occasionally the Packet Forwarding Engine(PFE) will restart.PR1705536

  • With GRES on a PTX running Junos OS Evolved, the current Label Edge Router role's scaling is suggested to be at 32,000 LSPs. When the number of LSPs get closers to 60,000 entries, the LC1201 evo-aftmand-bt process might run out of memory which causes the process to exit and the FPC restarts.PR1707063

  • On PTX10004, PTX10008, and PTX100016 Junos OS Evolved, hwdre core is generated when FTC(fan tray controller) is inserted. PR1724151

  • Changing Decap only tunnel destination address configuration after tunnel is up might not work or handled and end up using previously configured tunnel destination address for decapsulaton. Once system enters this state any further configuration changes to tunnel configuration will not be handled. PR1575724

Infrastructure

  • When using a source IP address as the management interface( with RPF check set to strict on interface), the response for the ICMP ping from the peer on the management interface is dropped by the Linux kernel as it expects the path to the peer to be on the WAN side. PR1498255

  • A Use After Free vulnerability in the kernel of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). Refer to https://kb.juniper.net/JSA70198 for more information. PR1636063

Network Management and Monitoring

  • When maximum-password-length is configured and the user tries to configure password whose length exceeds configured maximum-password-length, there is an error and the ok tag is emitted. (Ideally ok tag should not be emitted in an error scenario.) The configuration does not get committed. PR1585855

  • There is no service impact due to the failure of these test suites and these issues are not reported by any customer. These are silver creek hardening tests for Junos OS Evolved and issues raised by internal test team. PR1675251

  • There is no service impact due to the failure of these test suites and these issues are not reported by any customer. These are silver creek hardening tests for Junos OS Evolved and issues raised by internal test team. PR1675452

  • On Junos OS Evolved platforms, SNMP walk table (ipNetToMediaPhysAddress) is not updated when a neighbour entry is configured. PR1704878

Routing Policy and Firewall Filters

  • Delete single prefix from prefix-list will cause all the prefixes to be deleted. PR1691218

Routing Protocols

  • When l2cpd (in the context of xSTP) clears the entries that it has programmed on ppmd, that is when you delete xSTP configs from the box, there can be a possibility of ppmd core. If ppmd is in distributed mode then there will be no service impact, else there can be service impact as packet transmission for various protocols will happen through if ppmd is in centralized mode.PR1660299

User Interface and Configuration

  • The system might ask for your password when you are thing to save configuration file.PR1665008

  • Configd-streamer cores during commit of wild-carded groups related config. The core is only seen with the wild-carded configuration which is used in the reported fusion test case.PR1674890

  • In Junos OS Evolved, during scaled configuration commit, Configd daemon in UI-infra is taking more time to process the commit. To optimise the processing time, most likely there will be design change required. There is no LKWR/pass instance. Also based on the configuration scale and the time taken for the commit to complete, it seems that this is a Day-1 issue.PR1701214
