Here is the strange config. We have two site running BGP. one site is primary..now-both site learn same routes from the cloud but backup site prepands AS# to all routes learned from the cloud -in (yes in not out) than redistributes that to EIGRP. Primary site also redistributes BGP into EIGRP. Both sites use same metrics while redistributing. Please if you can tell me if that prepanding done on backup router influences how the BGP is redistributed? how ? I'm looking why backup site to get to subnets learned from BGP gets to them through the primary site - EIGRP..so it takes the route from primary as better route for that subnet. Did that prepand affected how backup router redistributes?
