300-620 Exam Dumps : Implementing Cisco Application Centric Infrastructure (300-620 DCACI)

 To allow multiple external networks to communicate with internal ACI subnets and assign the prefix to the class ID of the external Endpoint Group, the engineer should configure subnets with the External Subnets for External EPG flag enabled1. This configuration allows the specified subnets to be associated with an external EPG, which facilitates communication between internal tenants and external routed networks via L3Outs1.

To advertise a bridge domain subnet out of the ACI fabric to an OSPF neighbor, the following configuration steps are required:

Configure Subnet scope to Advertised Externally: This step involves setting the scope of the subnet within the bridge domain to be advertised externally, which allows the subnet to be propagated to external routing entities3.

Add L30ut profile to the bridge domain using Associated L30uts section: This step involves associating the bridge domain with an L3Out profile, which is necessary for the bridge domain subnet to be advertised to OSPF neighbors4.

To prevent frequent MAC and IP address moves between different leaf switch ports, enabling rogue endpoint control is the recommended action. This feature helps in identifying and mitigating the movement of endpoints that could potentially cause loops or other issues within the network.
