General Routing

  • FIPS mode is not supported. PR1530951

  • Enabling MPLS traffic engineering will cause LDP session not to come up, the reason behind is that the underlying TCP connection stays at SYN-SENT state. Disabling or deactivating the MPLS traffic engineering will solve this issue. PR1617629

  • On Junos OS Evolved platforms, when NDP (neighbor discovery protocol) entries are scaled to 32000 over IRB in one shot, NDP process might reach to 100% CPU utilization and unicast nexthops for all 32000 entries might not be present. This will result in traffic drops for entries for which unicast nexthop is not present. PR1551644

Layer 2 Ethernet Services

  • It was observed rarely that issuing a request system zeroize did not trigger ZTP. A simple workaround is to reinitiate ZTP. PR1529246

Routing Protocols

  • On Junos OS Evolved platforms, an rpd crash might be seen after reboot of the Junos OS Evolved device when MSDP is enabled. This might cause traffic drop until rpd comes up after the crash and restores all the routes. PR1536593
