Which command enables association between BFD and VRRP?

• A. vrrp vrid 1 track bfd-session session-name 1 reduced 100
• B. bfd-session vrrp vrid 1 track session-name 1 reduced 100
• C. track vrrp vrid 1 bfd-session session-name 1 reduced 100
• D. vrrp vrid 1 track bfd-session-name 1 reduced 100

Answer: (A)

The command that enables the association between Bidirectional Forwarding Detection (BFD) and Virtual Router Redundancy Protocol (VRRP) is structured to specify the VRRP instance and tie it to a specific BFD session. The correct choice does this by using the structure: - **vrrp vrid 1**: This indicates that the command is configuring VRRP for the virtual router ID of '1'. - **track bfd-session session-name 1**: This specifies that a BFD session, effectively named 'session-name' and identified as '1', is being tracked. The inclusion of the **reduced 100** element signals that the VRRP preemption will be influenced by the state of the BFD session, where '100' denotes a specific timing parameter. Thus, when the BFD session fails or encounters issues, the VRRP configuration becomes aware of it, allowing for failover procedures to occur seamlessly. This structure of the command ensures that the VRRP instance is directly monitoring the operational status of the BFD session, thereby enhancing redundancy and rapid convergence on the network, which is crucial in maintaining high availability. The other options do not properly format the command or misplace the structure, leading to
