The following configurations are present: -bgp inject-map exist-map -neighbor soft-reconfiguration in -neighbor route-map in Additional conditions: The route that matches the condition for the inject-map must be received from more than one neighbor, within a small time window. Additionally, the injected routes must be rejected by the neighbor's inbound configuration in order to hit the issue. Triggers: -clear ip bgp * soft -Conditions met at the time BGP comes out of Read-only mode (after reload)
remove soft-reconfiguration and hard clearing the peer
