The source MAC and IP address of the traffic is learned as a local endpoint.

The source MAC address of the traffic is learned as a remote endpoint.

No source MAC or IP address of the traffic is learned as a remote endpoint.

The source IP address of the traffic is learned as a remote endpoint.

It disables remote IP endpoint learning on all leaf nodes in the fabric.

It disables remote IP endpoint learning on leaf switches that do not have L3Outs.

It limits learning of compute leaf endpoints on border leaves.

It prevents border leaf switches from receiving routes through peering with external routers.

Change the contract scope to Global.

Enable the Shared between VRFs option for the BD subnet in the production VRF.

Enable the Shared between VRFs option for the EPG subnet in the non-production VRF.

Export the contract from provider to consumer tenant.

It is forwarded to one of the spines to perform as a spine proxy.

It is flooded within the whole fabric.

It is dropped by the leaf when the destination endpoint is not present in the endpoint table.

It is forwarded to one of the APICs to perform as a proxy.

Enable the BPDU interface controls under the spanning tree interface policy.

Configure a new STP interface policy.

Bind the spanning tree policy to the switch policy group.

Associate the STP interface policy to the appropriate interface policy group.

Create a new region policy under the spanning tree policy.

Map VLAN range to MAT instance number.

Delete both external EPG subnets.

Create the 0.0.0.0/1 subnet.

Delete the external EPG subnet 0.0.0.128/1.

Create the 128.0.0.0/1 subnet.

Delete both external EPG subnets.

Create the 0.0.0.0/0 subnet.

Delete the external EPG subnet 0.0.0.0/0.

ACI underlay protocols, i.e. COOP, IS-IS and MP-BGP, spans across pods. Create QoS policies to make sure those protocols have higher priority.

A single APIC Cluster is required in a Multi-Pod design. It is important to place the APIC Controllers in different locations in order to maximize redundancy and reliability.

ACI Multi-Pod requires an IP Network supporting PIM-Bidir.

ACI Multi-Pod does not support Firewall Clusters across Pods. Firewall Clusters should always be local.

Multi-Pod requires multiple APIC Controller Clusters, one per pod. Make sure those clusters can communicate to each other through a highly available connection.

The policy is downloaded and programmed in the hardware policy CAM when the change is implemented on the Cisco APIC.

The policy is programmed in the hardware policy CAM when the policy is downloaded in the leaf software.

The policy is programmed in the hardware policy CAM when the first packet is received through the data path.

The policy is downloaded to the associated leaf switch software when the ESXi host is attached to a DVS.

Notifications for different scopes of syslog objects can be sent only to one destination.

Syslog messages are sent to the destination through the spine.

All syslog messages are sent to the destination through APIC.

Switches send syslog messages directly to the destinations.

Associate the VMM domain with the EPGs that must be available in vCenter.

Assign the uplinks of the ESXi hosts to the vDS that the APIC created.

Configure contracts for the EPGs that are required on the ESXi hosts.

Create the port groups on the vCenter that reflect the EPG names in the APIC.

The Multi-Site orchestrator must be directly attached to one ACI leaf.

Routers in the Inter-Site network must run OSPF, DHCP relay, and MP-BGP.

ACI Multi-Site is a solution that supports a dedicated APIC cluster per site.

ACI Multi-Site is a solution that allows one APIC cluster to manage multiple ACI sites.

The Inter-Site network routers should run OSPF to establish peering with the spines.

Create an interface profile for the interface that disables LLDP on the desired switch that is referenced by the interface policy group.

Use VLAN 101 for OSPF adjacency on the egress L3Out.

Use VLAN 102 as the encap VLAN on the EPG-101 static port binding.
