On Junos platforms and Junos Evolved platforms, if a BGP peer goes down and stays down, the system might take an extremely long time to complete removing the BGP routes. The issue is observed when a BGP peer sends many routes, only a small number of routes are selected as the active routes in the routing information base (RIB, also known as the routing table), and if the BGP delete job gets only a small part of the CPU time because other work in the routing process is utilizing the CPU.PR1695062
