In a controller-based network, which routing protocol's functions are most likely moved to the centralized controller?

• A. SNMP
• B. SYSLOG
• C. EIGRP
• D. SSH

Answer: (C)

In controller-based networks, the control plane is centralized in the controller, which determines the best paths and installs forwarding rules on the switches. Routing protocols perform neighbor discovery, topology exchange, and route computation; moving those functions to the centralized controller means the controller handles the heavy lifting of route decisions instead of each router exchanging routing information. EIGRP is the routing protocol among the options, so its routing functions would be centralized in the controller. The other options are management or access protocols—SNMP is for monitoring, SYSLOG is for logging, and SSH is for secure remote access—so they aren’t the routing processes that would be moved to the controller.
