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

To advertise the 0.0.0.0/0 prefix out on L3Out-2 OSPF, when it is configured as a default static route on L3Out-1, the action that should be taken is to enable the Export Route Control Subnet. This setting allows the default route to be advertised to other L3Outs, enabling the ACI fabric to act as a transit network1.

ACI Fabric L3Out White Paper - Cisco1

To enable communication between the external subnet and internal EPG1, and to allow L3Out traffic to leak into the VRF named “VF1”, the following configuration set should be used:

External Subnets for External EPG: This configuration defines the subnets that are external to the ACI fabric but need to be reachable from within the fabric. It is necessary to specify which subnets are to be considered part of the L3Out1.

Shared Route Control Subnet: This setting allows the subnets to be shared across different VRFs, enabling communication between EPGs that are in different tenants but within the same VRF1.

Shared Security Import Subnet: This configuration ensures that the security policies (contracts) associated with the shared subnets are also imported, allowing for the necessary traffic to flow between the internal and external endpoints1.

By applying this configuration set, the external subnet and internal EPG1 will be able to communicate, and the L3Out traffic will be properly leaked into the designated VRF, meeting the specified goals.

To clear the critical fault related to B2B credit oversubscription in the ACI domain connectivity to the fiber channel storage, the value that should be chosen is 5101. This value is set to address the issue of B2B credit oversubscription and clear the critical fault as reported by the client1.
