General Routing

  • On WRL8 based VMHost platforms (i.e., ACX6360/PTX10001/MX150/NFX150/NFX250/NFX350), there is no log rotation for resild log and temperature sensor info is incorrectly written into resild log which could result in continuous logs in resild log file. The disk usage might keep increasing due to this issue. The disk usage could be eventually full which could cause system to hang and reboot. PR1480217

  • In the platform using indirect next-hop (INH), such as Unilist as route next hop type for multiple paths scenario (such as BGP PIC or ECMP), the session fast-reroute might be enabled in Packet Forwarding Engines. When the version-id of session-id of INH is above 256, the Packet Forwarding Engine might not respond to session update, which might cause the session-id permanently to be stuck with the weight of 65535 in Packet Forwarding Engine. It might lead Packet Forwarding Engine to have a different view of Unilist against load-balance selectors. Then either the BGP PIC or the ECMP-FRR might not work properly and traffic might be dropped or silently discarded. PR1501817

  • On Junos OS platforms supporting GRES, the bandwidth flag on the backup Routing Engine for the aggregated Ethernet interfaces is set unconditionally. Therefore, the BW is struck at a value despite not being set by the user statically. When GRES is performed followed by link delete/add for the aggregated Ethernet interface, the interface might get stuck with the BW and gets synced with the backup RE. There can be seen partial service impact in the case of the RSVP (Resource Reservation Protocol) and the restoration to recover from this issue is to configure bandwidth manually and then remove the configuration.PR1649958

  • In a scenario where static routes are added with varying weight values and verified, rpd core file is generated. rpd is recovered automatically and restarted by jlaunchd.PR1699356

Multicast

  • On Junos OS PTX Series platforms traffic might slilent drop because of the next-hop installation failure for multicast RSVP point to multipoint (P2MP) traffic. This issue might encounter in a scaled RSVP P2MP environment after a network event which might cause reconvergence. PR1653920
