A bit late but we (Cisco) do have some folks running ORR but not many.
Recently I worked with a large provider and in the end they decided
to just distribute RRs across their network instead. I’m not aware of
any limitations with the ASR9K specifically in regards to ORR, there
is no silicon dependence with ORR in IOS-XR. It’s what we would call
a platform-independent function.
However, we typically recommend folks look at the RR appliance or
XRv9K/xRD for RR use cases since the general CPUs are much more
powerful than the ones we put into a router RP.
In my day, the only ASR9000 we had was the ASR9001 client.
Try as we might, it couldn't be part of our BGP Add-Paths
infrastructure. Not enough control plane resources to hold more than one
full table in 2023.
While I imagine the Intel-based ASR9000 routers are much more powerful
as a client, I agree that running a route reflector on compute is the
best way forward.
Mark.
