Junos OS Evolved PTX platforms fail to relearn MAC after interface mac limit is reached
Product-Group=evo
On all Junos OS Evolved PTX platforms, when 'interface-mac-limit' is configured, the interface fails to learn new MAC addresses when MAC address table gets cleared because the MAC-limit has been reached. This results in disruption of unicast traffic forwarding.

Evolved is using old MAC address for forwarding leading to traffic drops
Product-Group=evo
On Junos Evolved platforms with VXLAN (Virtual Extensible LAN) configuration, traffic drops because the ICMP (Internet Control Message Protocol) response is going with old/stale MAC (Media Access Control) address.

A high CPU consumption of mcsnoopd process is seen under IGMP-snooping configured scenario leading to its crash
Product-Group=evo
On all Junos and Junos OS Evolved platforms with IGMP-snooping (Internet Group Management Protocol) enabled under instance type EVPN (Ethernet Virtual Private Network) with vlan-id=none or unspecified vlan-id there will be a spike in the mcsnoopd process CPU utilization. This will lead to the mcsnoopd process crash and there will be disruptions in the traffic.
1723832
The rpd core is seen in the long-running devices with EVPN enabled
Product-Group=evo
On Junos and Junos Evolved platforms, BGP (Border Gateway Protocol) community object reference count is not handled properly during the process of remote BGP peer routes update event. The community reference count is increasing during the increment function. However, decrement functions are not called in one of the places after processing the routes update. This will lead to a disturbance of the continuity reference count, which will cause an rpd crash.

Convergence delay is seen when FPC is offlined under heavy traffic and scaled scenario
Product-Group=evo
On Junos PTX3000, PTX5000, PTX10008, and PTX10016 routers, when the Flexible PIC Concentrator (FPC) is offlined with scale configuration and heavy traffic, a delay in convergence (into tens of minutes) is seen on all the live FPCs in the chassis other than the offlined one. This impacts traffic.
