https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/1-x/ACI_Best_Practices/b_ACI_Best_Practices/To redistribute externally learned OSPF routes within the ACI fabric, the correct answer is A. Route Control Profile.
Cisco ACI (Application Centric Infrastructure) is a software-defined networking solution that provides a policy-driven automation framework for deploying and managing applications across physical and virtual environments. ACI provides a centralized point of management for network infrastructure, including routing, switching, and security.
When OSPF (Open Shortest Path First) is used as the routing protocol within the ACI fabric, it is possible to redistribute externally learned OSPF routes into the ACI fabric using a Route Control Profile. A Route Control Profile is a policy construct that defines how routing information is exchanged between different routing domains within the ACI fabric.
To configure a Route Control Profile for OSPF redistribution, the following steps should be taken:
Create a Route Control Profile: This can be done using the ACI GUI or the CLI (Command Line Interface). In the ACI GUI, navigate to Fabric > Access Policies > Policies > Route Control Profiles. Click the + button to create a new profile and give it a name.
Add OSPF as a Routing Protocol: In the Route Control Profile, select OSPF as a routing protocol. This will allow the ACI fabric to understand OSPF routes.
Configure Redistribution Settings: Under the Redistribution Settings section, configure the redistribution options for OSPF. This includes selecting the external routing protocol (in this case, OSPF) and defining redistribution filters, which specify which OSPF routes should be redistributed into the ACI fabric.
Apply the Route Control Profile: Once the Route Control Profile has been configured, it must be applied to the appropriate interfaces or VRFs (Virtual Routing and Forwarding). This can be done using the ACI GUI or the CLI.
By configuring a Route Control Profile, OSPF routes learned from external routing domains can be redistributed into the ACI fabric. This enables greater flexibility in designing and deploying networks within the ACI fabric, as it allows for integration with existing networks and services.
