Question 43/107

When creating a single-hop BFD session for the first time, bind the single-hop BFD session to the peer IP address and the local address. To modify a configured BFD session, delete it and create a new one.

A. TRUE

B. FALSE

Correct Answer: A

Comprehensive and Detailed Step-by-Step Explanation:
1. Single-Hop BFD Session:
* A single-hop BFD session is used to detect link failures between directly connected devices.
* It is bound to the local IP address and the peer IP address, and the session relies on these parameters to establish connectivity.
2. Why Modifications Require Deletion:
* BFD sessions are tightly bound to their configuration parameters (e.g., local and peer IP addresses).
* Modifying these parameters is not supported for an existing session. Instead, you must delete the session and recreate it with the updated parameters.
3. Why the Statement is TRUE:
* The statement correctly describes the behavior of BFD sessions, where modifying an existing session is not possible without deleting it first.
