Thanks everyone for your inputs. So bottomline setup RPKI and setup ROA's for all our subnets being advertised. Much of this is legacy and has too many unknowns, being handed down networks without documentation also does not help. Thanks, Sam On Tue, Nov 1, 2022 at 9:07 AM heasley wrote: > Tue

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. Kevin Burke 802-540-0979 Burlington Telecom 200
