Question 230
At the Silverstream data center, EIGRP hellos pass across the transit link, yet R-SIL-PE1 never forms a neighbor with R-RIV-PE2; the peers use different EIGRP AS numbers. Which underlying technical condition best accounts for this evidence?
Explanation
Correct Answer
This diagnosis fits the symptoms at the Silverstream data center. EIGRP peers in different AS configurations will not establish the intended neighbor relationship. The remedial action is: Configure matching EIGRP autonomous-system values for the participating adjacency.
Incorrect Answers
The observation at the Silverstream data center does not point to eigrp query scope using stub; it points to a different condition. EIGRP peers in different AS configurations will not establish the intended neighbor relationship.
This diagnoses a different mechanism: Default EIGRP forwarding does not use the desired unequal-cost feasible alternate without appropriate variance. The reported symptom at the Silverstream data center instead concerns eigrp as mismatch.
That diagnosis belongs to eigrp delay in composite metric, while the observation at the Silverstream data center points to eigrp as mismatch.
