Juniper released BGP ORR for ISIS in 15.1F4: Support for BGP Optimal Route Reflection (BGP-ORR) (MX Series)—Starting with Junos OS Release 15.1F4, you can configure BGP-ORR with IS-IS as the interior gateway protocol (IGP) on a route reflector to advertise the best path to the BGP-ORR client groups by using the shortest IGP metric from a client's perspective, instead of the route reflector's view
