ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 151

Which value must you configure on a device before EIGRP for IPv6 can start running?

Answer options

• A. public IP address
• B. loopback interface
• C. router ID
• D. process ID

Correct answer: C

Explanation

The router ID is essential for EIGRP to function, as it uniquely identifies the router within the EIGRP routing domain. The other options, such as public IP address, loopback interface, and process ID, are not mandatory for starting EIGRP for IPv6, although they may be useful in certain configurations.
