Question 410
At the Lakeside transit hub, OSPF routes enter EIGRP through R-LAK-CORE1 and are later returned to OSPF at the East depot network, producing unstable preferred paths to 10.32.0.0/16. After remediation, which observation would most directly demonstrate the intended result?
Explanation
Correct Answer
This tests the exact behavior that was failing at the Lakeside transit hub. Routes retain an origin tag and the return redistribution point rejects already-imported routes. The change supporting that outcome is: Tag redistributed routes at entry and filter those tags from re-entering their origin protocol.
Incorrect Answers
That test could pass while the specific fault remains. The intended prefix appears as the expected external route while unrelated partner prefixes stay absent. It would not establish the required outcome for redistribution loop route tagging at the Lakeside transit hub.
The result addresses ospf area range configured on wrong border, not the observed fault at the Lakeside transit hub. The decisive outcome is different: Routes retain an origin tag and the return redistribution point rejects already-imported routes.
That test could pass while the specific fault remains. Each prefix covered by the aggregate has a valid forwarding path, or the aggregate is appropriately withdrawn. It would not establish the required outcome for redistribution loop route tagging at the Lakeside transit hub.
