Explanation

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.
