Usage guidelines
An external route is a route to a destination outside the OSPFv3 AS. External routes include the
following types:
•
Type-1 external routes—Have high credibility. The cost of Type-1 external routes is
comparable with the cost of OSPFv3 internal routes. The cost of a Type-1 external route equals
the cost from the router to the ASBR plus the cost from the ASBR to the external route's
destination.
•
Type-2 external routes—Have low credibility. OSPFv3 considers the cost from the ASBR to a
Type-2 external route is much bigger than the cost from the ASBR to an OSPFv3 internal router.
The cost of a Type-2 external route equals the cost from the ASBR to the Type-2 external
route's destination.
