General Routing
On all MX devices, traffic might be interrupted when you change the configuration from AMS warm-standby to AMS deterministic NAT. PR1597386
MPLS
With local reversion ON, there is a possibility of transit router not informing headend of RSVP disabled link when link flaps more than once. As a workaround, remove the local-reversion configuration.PR1576979
The automatic sorting of configuration entries does not work if defined under a group. PR1637730
Platform and Infrastructure
Major alarm with XQCHIP(46):XQ-chip[0]: DROP protect_regs error (status=0x8) logs appears. PR1303489
On MX series devices, under Ethernet VPN (EVPN) environment, packets routed using IRB interface could not be fragmented due to media maximum transmission unit (MTU) problem. PR1522896
Deactivating services rpm/rpm-tracking does not remove the tracked route from the routing or forwarding tables. PR1597190
Routing Engine-based BFD sessions might flap during switchover when there are large number of BFD, IS-IS, OSPF and LDP packets to be sent out. PR1600684
Routing Policy and Firewall Filters
When a hierarchy specified in apply-path is configured in an ephemeral instance, then rpd might not be able to update the prefix-list for the configuration in ephemeral instance. PR1636390
Routing Protocols
When we have high scale, the openconfig telemetry sensor /bgp-rib/ used in periodic streaming will cause high cpu usage by RPD. PR1625396
When routing-options transport-class fallback is not configured, do not configure more than 10 transport-classes or advertise more than 10 distinct colors in SR-TE or FlexAlgo. PR1648490
