Junos - or specifically Filter-based Forwarding (FBF) - takes a very different approach to achieving this, which may take your "Cisco brain" a bit of context-switching to adapt to, namely: On Cisco gear, this is normally achieved via Route Maps or Route Policy Language (RPL) matching Access Control Lists (ACLs), Prefix Lists, Interfaces or some other attribute to match the desired traffic flows to "PBR" away from normal Routing. If you're a Cisco Guy (or Girl, I'm not biased both sexes are welcome to the Cisco Pain Train), you'll likely have come across a need for Policy Based Routing (PBR) to change the normal Destination IP-based logic of Network Routing to instead be a Source-IP or Interface-based logic, for some purpose of bypass.
