To implement the inter-tenant service graph, the set of actions that must be taken are:

Define the contract in the provider tenant and export it to the consumer tenant (Option B).

Define the L4-L7 device and service graph template in the provider tenant and the ASA bridge domains in the consumer tenant (Option B).

This approach allows for the proper configuration and association of the service graph between the provider and consumer tenants, ensuring that the services are correctly applied to the traffic flowing between them.

The two IP address types that are available for transport over the Inter-Site Network (ISN) when they are configured from Cisco ACI Multi-Site Orchestrator (MSO) are the Anycast Overlay Multicast Tunnel Endpoint (TEP) and the MP-BGP EVPN Router-ID. These IP addresses are used for inter-site communication and routing in a Multi-Site deployment.

 The statement about the MTU value of MP-BGP EVPN control plane packets in Cisco ACI that is true for communication between spine nodes in different sites is that by default, spine nodes generate 9000-bytes packets to exchange endpoints routing information. As a result, the Inter-Site network should be able to carry 9000-bytes packets2. This ensures that the control plane traffic, which is not VXLAN encapsulated, can be properly handled across the sites2.

The method that the Cisco ACI fabric uses to load-balance multidestination traffic is forwarding tag trees3. This method involves assigning a forwarding tag (FTAG) to the traffic when it is forwarded within the fabric, ensuring efficient load balancing of multi-destination traffic3.

To meet the requirement of sending all faults and events related to endpoint groups, bridge domains, and VRFs to the new SNMP configuration and syslog servers, the network engineer should utilizecommon tenant monitoring policies in the Cisco APIC. The common tenant is used for global configurations that apply across the entire fabric, including monitoring policies.

When configuring in-band management IP addresses for Cisco APICs, leaf nodes, and spine nodes, the tenant used is the mgmt tenant1.

To move the gateway address for VLAN 1001 from the core outside the Cisco ACI fabric into the Cisco ACI fabric and ensure that endpoints in EPG-1001 route traffic to endpoints in other EPGs while minimizing flooded traffic in the fabric, the following configuration set is needed on the bridge domain:

Enable Hardware Proxy: This step involves enabling the hardware proxy feature, which allows the fabric to learn and maintain endpoint information more efficiently7.

Enable Unicast Routing: This step involves enabling unicast routing within the bridge domain, which allows for the routing of traffic between different EPGs and minimizes flooded traffic

To implement the Inter-Site Network (ISN) for a Cisco ACI Multi-Site deployment, the following configuration steps are essential:

Configure OSPF on all ISN routers: OSPF (Open Shortest Path First) is a routing protocol that is used to ensure that all routers in the ISN have the necessary routing information to forward packets between sites.

Configure BIDIR-PIM on all ISN routers: BIDIR-PIM (Bidirectional Protocol Independent Multicast) is used for efficient multicast traffic forwarding across the ISN. This is particularly important for Cisco ACI Multi-Site deployments as it supports the replication of broadcast, unknown unicast, and multicast (BUM) traffic across sites.

 When the VMM resolution immediacy is set to pre-provision in a Cisco ACI environment, policies are downloaded to the ACI leaf switch regardless of Cisco Discovery Protocol neighborship1. This setting ensures that the policies are in place on the leaf switches even before a VM controller is attached to the virtual switch1.

The two dynamic routing protocols supported when using Cisco ACI to connect to an external Layer 3 network are iBGP (Option A) and eBGP (Option E)78. These protocols are included in the routing protocol options for a Layer 3 external outside network configuration in ACI
