Description

Currently, the LinkStateRoutingTableCalculator does not account for links that have different costs in advertised adjacency LSAs.

If Router A's adjacency LSA has Router B listed as an adjacency with cost 10 and Router B does not have adjacency A listed in its adjacency LSA, the calculator will still consider the link between A and B as valid.

Instead, the calculator should correct these issues by using the minimum of the two costs.

In the above case, this would mean considering the link between Router A and Router B as down.
