Question 9/107

By default, if no router ID is configured but multiple loopback interface addresses are configured, BGP selects the largest loopback interface address as the router ID.

A. TRUE

B. FALSE

Correct Answer: A

Comprehensive and Detailed Step-by-Step Explanation:
* BGP Router ID Selection Rules:
* If a router ID is not manually configured:
* The largest loopback address is selected as the router ID.
* If no loopback interfaces exist, the largest active physical interface address is selected.
* Default Behavior:
* This ensures that a stable and unique router ID is chosen automatically, even without manual configuration.
