E1 or External Type Routes – The cost of E1 routes is the cost of the external metric with the additional of the internal cost within OSPF to reach that network.
If 2 external type 2 routes exist with the same metric to the same destination the route with the lowest metric to the ASBRwill be used. Also if an E1 and E2 route exist to the same destination the E1 route will always be preferred irrespective of the metric.
