Consider only synchronized routes with no AS loops and a valid next hop, and then:

1.- Prefer highest weight (local router).
2.- Prefer highest local preference (global within AS).
3.- Prefer route originated by the local router (next hop: 0.0.0.0).
4.- Prefer shortest AS path.
5.- Prefer lowest origin code (IGP<EGP<Incomplete).
6.- Prefer lowest MED (metric, exchanged between autonomous systems).
7.- Prefer eBGP path over iBGP path.
8.- Prefer the path through the closest IGP neighbor (IGP cost).
9.- Prefer oldest route for eBGP paths.
10.- Prefer the path with the lowest BGP neighbor's Router ID.
11.- Prefer the path with the lowest neighbor IP address.
