RE: Understanding impact of RPKI and ROA on existing advertisements

You may want to set this up yourself anyways.  In the effort of making things work, your upstream ISP may have had to 
setup these records on your behalf.  If not now, they may in the future.  Having duplicate entries can cause unexpected 
results.

Subject: Understanding impact of RPKI and ROA on existing advertisements

Hello,
I am new to RPKI/ROA and still learning about RPKI. From all my reading on ARIN's documents I am not able to answer 
some of my questions.
We have a public ARIN block and advertise smaller subnets from that to our ISP's. We do not have any RPKI configs.
We need to setup ROA's to take another subnet from the ARIN block to AWS. Reading ARIN's docs, it seems I need to get 
setup on their Hosted RPKI service after which I can configure ROA's for the networks I am taking to AWS.

My question is, will this impact my existing advertisements to my ISP's. The current advertisements do not have ROA's.
Will having RPKI for my ARIN network, without ROA's for the existing advertisements impact me?

Thanks for your help.
