When both OSPF E1 (External Type 1) and E2 (External Type 2) routes exist to the same destination with equal cost, the router always prefers the E1 path. This is because E1 routes include both the external cost and the internal OSPF cost to reach the ASBR, making them more accurate for path selection.
