In a multihomed OTV network, it is essential to configure the remote OTV AEDs (Authoritative Edge Devices) to use both the primary and secondary adjacency servers for redundancy and resiliency. The correct configuration, Option D, includes the otv use-adjacency-server command with both IP addresses of the primary and secondary servers followed by unicast-only, which indicates that the AEDs should use unicast connections to the adjacency servers instead of multicast. References := This configuration aligns with best practices for setting up OTV networks as described in Cisco's Data Center Core Technologies documentation. For a more comprehensive understanding, refer to the study materials related to OTV configurations in the Cisco Data Center Core Technologies (DCCOR) course.
