Traffic 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.

Traffic 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.
