Traditional Network Implementation in Cisco ACI

Configure Policy-Based Redirect to Layer 4–Layer 7 Service Node

In this lab, you will deploy the Cisco Adaptive Security Virtual Appliance (ASAv) as a firewall service in the Cisco ACI fabric. You will use policy-based redirect (PBR) to bend the traffic from DB_EPG to BACKUP_EPG to go through the Cisco ASAv as shown in the following figure.

Cisco ACI will configure VLANs on the leaf interfaces connected to Cisco ASAv along with the required redirection rules on leaf switches. Cisco ACI will not touch the Cisco ASAv configuration, being out of its management scope.

In the logical view shown above, traffic between DB_VM and BACKUP_VM would be normally routed by Cisco ACI without ACI Service Graph PBR, because Cisco ACI is the default gateway. You will use Cisco ACI Service Graph PBR to selectively force the traffic to go through Cisco ASAv.

Deploy Multi-Pod Fabric

The correct answers are DHCP relay support, Increased MTU support, and OSPF support between the spine switches and IPN routers. In Cisco Multi-Pod deployment, the IPN must support PIM Bidir, OSPF support between spine switches and IPN routers, DHCP relay, increased MTU, and so on. However, it is not required to support PIM ASM, EIGRP, or BGP between the spine switches and IPN routers.

The correct answer is BGP in each pod runs in the same BGP AS. The MP-BGP that runs directly between spine switches in each pod is in the same BGP AS. Thus, the pods cannot use different BGP AS. Also, the IPN devices do not participate in this BGP session, but it just provides TEP reachability to establish BGP sessions between each spine switch. Finally, you can use route reflector nodes in each pod (recommended for resiliency) so that the spine nodes only peer with the remote route reflector nodes, and a full mesh of MP-BGP session is then established only between the route reflectors.
