 To enable communication between the subnets 192.168.1.0/24 and 172.18.1.0/24 using Cisco ACI fabric, it is necessary to configure the subnets appropriately. For option B, setting 172.18.1.0/24 as an External subnet for an external EPG under L3out_A allows it to be recognized as part of an external network, facilitating communication with other networks within the ACI environment. Similarly, for option D, configuring 172.18.1.0/24 with the Export Route Control scope under L3out_B ensures that this route is advertised out of L3out_B, allowing it to reach other network segments, including those connected via L3out_A where the subnet 192.168.1.0/24 resides. These configurations are crucial for proper routing between these two distinct subnets across the Cisco ACI fabric.

PBR Node Tracking:

Purpose: It is used to monitor the health and availability of endpoints within an Endpoint Group (EPG).

Functionality: When configured, it allows for real-time health checks and traffic redirection based on endpoint status and network conditions.

Benefits: Ensures traffic is directed to healthy endpoints, maintaining application performance and availability.

In Cisco ACI, Virtual Routing and Forwarding (VRF) instances are used to create separate routing tables for network traffic management. An unenforced VRF does not apply policies or contracts for communication between endpoints, allowing free communication without the need for explicit permissions. By implementing an unenforced VRF in the common tenant and mapping all required Bridge Domains (BDs) to it, each department’s BDs can communicate with one another without configuring contracts or VRF route leaking, thus meeting the company’s requirement for redesigning their networking architecture. References: Implementing Cisco Application Centric Infrastructure Official Cert Guide
