    3. Highest active configured IPv4 address
  • 1. Highest IPv4 loopback address
    2. Highest active configured IPv4 address
    3. Router ID that is explicitly configured

Explanation: The correct order of precedence for choosing the router ID is as follows:

1. The router ID is explicitly configured using the OSPF router-id rid router configuration mode command.
2. If the router ID is not explicitly configured, the router chooses the highest IPv4 address of any of the configured loopback interfaces.
3. If no loopback interfaces are configured, then the router chooses the highest active IPv4 address of any of its physical interfaces.
