It's two things specifically for us - RPL construction in IOS XR can be 
done in Junos for half the number of lines to achieve the same outcome, 
without losing sophistication.

Secondly, maintaining IOS XR (upgrades and SMU's) is too tedious.

They may seem like trivial points, but for us, they mean a lot.

It's why we still prefer IOS XE (by way of the CSR1000v) as a route 
reflector vs. Junos or IOS XR. IOS XE is far less verbose than the other 
two, in that role.
