Which criterion is preferred by the router to choose a router ID?

  • the IP address of the highest configured loopback interface on the router
  • the IP address of the highest active interface on the router
  • the router-id rid command
  • the IP address of the highest active OSPF-enabled interface

Explanation: The preferred order of criteria for Cisco routers to identify the router ID is: an explicitly configured router using the router-id rid command; the IP address of any configured loopback interface; and the IP address of any active interface on the router (it does not have to be an OSPF-enabled interface).
