CCNP Certification / BSCI Exam:
DUAL has unconcealed four researchable paths to a far network, with the consequent metrics: PathA, 1500. PathB, 1500. PathC, 2600. PathD, 3100. What tell will permit EIGRP to use the front three paths lacking exploitation the fourth?
Answer: discrepancy 2 would do the job. Any towpath beside a metrical of 3000 or lower will be utilized; setting it to 3 would distribute PathD into the mathematical statement.
