A network administrator can set the OSPF metric-type on an AOS-Switch to Type 1 or Type 2. What is the difference?

A Type 2 metric stays the same as the external route is advertised, while a Type 1 metric increments with internal OSPF link costs. This means that Type 2 metrics consider only the external cost assigned by the ASBR, ignoring any internal OSPF costs for reaching the ASBR. Conversely, Type 1 metrics combine both the internal OSPF cost to reach the ASBR and the external cost assigned by the ASBR, resulting in a more comprehensive total cost representation.
The difference between the two is in the way the cost (metric) of the route is being calculated. The cost of a type 2 route is always the external cost, irrespective of the interior cost to reach that route. A type 1 cost is the addition of the external cost and the internal cost used to reach that route. Correct D
Type 1 LSA, with information about its own OSPF networks, or links, and the cost of using those links. Type 2, LSA with information about all the routers on that network
Type 1 adds every "link" along the path from the area router to the external network. Where a Type 2 adopts the metric (An ASBR may have ... OSPF Area 1 redistribute connected). Tus, 3 links from internal router-ABR-ASVR would have a Type 1 - Metric 12; Type 2 - Metric 10) :).
