We use ORR and add-path 3 (to enable ECMP and to have backup) with about 40 ORR perspectives and +15M RIB. But this is Junos running on compute. You really want compute, not actual router hardware as the CPU gains from modern compute are very significant.
In my IP days (up until about 2 years ago), we ran Add-Paths on a Cisco CSR1000v (was in the process of transitioning to the 8000v) route reflector with Junos clients.
Worked very well that we did not need ORR, having up to 6 paths per client with BGP Multipath enabled as well.
Ate a lot of CPU and RAM on the clients, but I've since heard that those RE's were upgraded, so no more concern.
Being able to load balance traffic to the same AS across different cities/regions was very sweet. Opened up some new commercial opportunities the competition could not support.
