Company XYZ runs OSPF in their network. A design engineer decides to implement hot-potato routing architecture.

How can this implementation be achieved?
A . Enable iBGP and apply prepend to ensure all prefixes will have the same length of the AS path attribute value.
B. Redistribute the external prefixes onto OSPF and ensure the total metric calculation includes only the ext value and the value is the same in all ASBRs.
