Hi, If you are running "soft-reconfiguration inbound rpki-droppped-only" on IOS-XR7, please note CSCwb17937. We had a terrible time with this. Best regards, takez

Dear Guru(s),
We used to run our ‘Gateway Router’ with ROV turned on. Then, we “upgraded” it to a Cisco NCS-55A1 (5500 Series) running IOS-XR just a few weeks ago.
Consequently, during my rummage through Google for a (the?) best (ROV) configuration template for the new router, I found a tutorial by Philip Smith [Reference: https://www.bgp4all.com/pfs/_media/workshops/02-rpki.pdf, Slide #55] which cautioned me of Cisco IOS-XR essentially “harassing” all peers and upstreams with ‘Route Refresh’ whenever there is a VRP change. The tutorial advised turning on ‘Soft Reconfiguration’ to help with the problem.
On the one hand, we have a very special relationship with our upstream [they’re kind of community transit provider; we have an in-kind stake in them as well], so we obviously don’t want to cause them grievances [their grievance is our grievance]. On the other hand, we can't afford to just throw away a newly bought gateway and buy a new one.
So, here goes the question: Is setting 'Soft Reconfiguration' enough for me to keep ROV running? If not, is there any other solution? Or am I screwed anyway?
I would very much appreciate clarification and pointer(s) to the solution(s).
Thank you in advance for the help,
Pirawat.
