1695771Traffic loss is seen when a MAC moves from dot1x port to non-dot1x port
Product-Group=evo
On all Junos and Junos OS Evolved platforms is having dot1x enabled interface. When two or more MAC addresses are learnt on a dot1x port, and if one of them is shifted to a non-dot1x port, the MAC address that was moved is still seen as a MAC-based VLAN entry on the Layer2 Address Learning Manager (l2alm). This could lead to network traffic being lost.
PR NumberSynopsisCategory: Border Gateway Protocol
1695062Traffic blackholing is observed when removing the BGP routes take a long time to get removed from RIB
Product-Group=evo
On Junos platforms, if a BGP (Border Gateway Protocol) peer is going down and stays down and the system might take an extremely long time to complete removing the BGP routes. The issue observed when a BGP peer sends many routes, only a small amount of routes are selected as the active routes in the RIB (Routing Information Base), and if the BGP delete job gets only a small part of the CPU time as other work in the routing process utilize the CPU.

1682659The FPC can go to a fault state on certain Junos Evolved PTX platforms after system reboot
Product-Group=evo
On certain Junos Evolved PTX platforms FPC (Flexible PIC concentrator) goes to a fault state after a system reboots with a Major alarm - Power Failure. This issue is a rare issue and the FPC in a fault state will impact the data traffic. To recover from this issue the impacted FPCs need to be rebooted.

Product-Group=evo
With GRES on a PTX running Junos EVO, 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 may run out of memory which causes the process to exit and the FPC restarts.
