What operational feature is different for EIGRP for IPv6 compared to EIGRP for IPv4?
- the source and destination addresses used within the EIGRP messages
- neighbor discovery mechanisms
- router ID configuration
- DUAL algorithm calculations
Explanation: Most of the EIGRP operational features are the same for IPv6 as they are for IPv4. Both use the same DUAL algorithm calculations, metric values, neighbor discovery mechanisms, and 32-bit router ID. What is not the same between the protocols are the source and destination addresses used for EIGRP messages.
