Cisco 300-620 Exam With Confidence Using Practice Dumps

 To redistribute externally learned OSPF routes within the ACI fabric, a Route Control Profile must be configured1. This profile allows for the control of route redistribution and the application of route maps to influence routing decisions within the fabric1.

The scenario involves a tenant configured with a single L3Out and a single-homed link from the ACI fabric (via border leaf BL-1001) to a core router (Core-1). The engineer must add a second link to the L3Out, connecting to Core-2 via BL-1002, ensuring that traffic from Core-2 to BL-1002 has the same connectivity as traffic from Core-1 to BL-1001. The exhibit shows a single-homed setup with BL-1001 and BL-1002 as potential border leaves, with a dashed line indicating a planned second link.

Requirement Analysis

The existing L3Out is single-homed to Core-1 via BL-1001, and the goal is to extend it to a multi-homed configuration with Core-2 via BL-1002.

"Same connectivity" implies that the second link must be integrated into the existing L3Out configuration, sharing the same routing policies, external EPG, and subnet reachability.

The solution must leverage ACI’s L3Out framework to add the new path without creating a separate L3Out or altering the current routing setup unnecessarily.

Option Evaluation

A. Add a second path to the logical interface profile of the existing L3Out:

The logical interface profile in an L3Out defines the interfaces (e.g., routed ports or sub-interfaces) and their associations with nodes (border leaves). Adding a second path to this profile allows the inclusion of the new link from BL-1002 to Core-2, ensuring it operates under the same L3Out configuration (e.g., routing protocol, external EPG). This maintains consistent connectivity and leverages ACI’s multi-homing support.
