The technology disclosed herein enables multicast network traffic to pass an RPF check in a logical router having separated packet handlers. In a particular embodiment, a method includes, in a north/south packet handler of a first logical router, receiving first network traffic from an east/west packet handler of the logical router. The first network traffic is multicast network traffic and the logical router is a first hop router for the first network traffic from a source of the first network traffic. The method further includes identifying an entry for the source in unicast routing information for unicast network traffic. Identifying the entry indicates that the first network traffic passes a reverse path forwarding (RPF) check. In response to the first network traffic passing the RPF check, the method includes transferring the first network traffic from the north/south packet handler to a next hop for the first network traffic indicated by first multicast routing information.
