Refer to the exhibit. Which command set changes the neighbor state from Idle (Admin) to Active?

This configuration attempts to establish a neighbor relationship with itself (10.1.12.1 is R1's IP) as a peer with a remote AS of 65001, which is incorrect for peering with a different router in AS 65002, and it lacks the `no shut` command.

This configuration uses `neighbor 10.1.12.2 remote-as 65001`, incorrectly setting the remote AS to the local AS (assuming R1 is in AS 65001), and it lacks the `no shut` command to explicitly activate the neighbor.

The `no shut` command, applied under the specific BGP neighbor configuration, explicitly re-enables the BGP peering session, transitioning it from the administratively down (Idle Admin) state to active. The `neighbor 10.1.12.2 remote-as 65002` line ensures that the correct neighbor and its remote AS are configured, allowing the `no shut` command to apply to the intended peering.

This command set attempts to configure BGP for AS 65002 on R1, which is incorrect if R1 is in AS 65001, and the neighbor configuration specifies the remote AS incorrectly and lacks the `no shut` command.
