Just to clarify my question....
Router A-----------Router B------------Router C
Router B has the offset list adding 10 to the RD and FD for 10.1.1.0 updates coming in g0/0. Will router B advertise it's FD to 10.1.1.0 to Router C with the 10 added or will it be the actual cost w/o the added 10 from the offset list applied inbound on g0/0? I would lab this out but don't have the ability to right now. Replies would be greatly appreciated.
