And i'm wondering why step 7 exist (Prefer eBGP over iBGP paths) since when a router receive the same route via EBGP and IBGP, the administrative distance will break the tie (IBGP = 200, EBGP = 20) from the very start of the process, even before entering that BGP selection algorithm process.
Actually the Administrative Distance is applied to routes only as the routing protocol passes them to the process that builds the IP routing table. BGP has no concept of AD as it goes through the best path selection process. This is why step 7 exists.
as Rick says BGP has its own BGP table where all the paths are stored, the BGP selection is applied to this table and here the AD plays no role.
After BGP comes up with a best path to a prefix the process that mantains the routing table will label it with AD=20 or AD=200 depending if the path is external (comes from an eBGP session) or internal (comes from an iBGP session).
