Which of the following would cause the router to go active on a route?

  • The router receives an update containing information about a new prefix.
  • Border routers join the inactive route.
  • The EIGPR topology table refresh timer expires.
  • A route is lost but the router has no feasible successor available.

Explanation: A router transitions to the active state for a specific route when that route is lost and the topology table contains no feasible successor to provide an immediate alternative path. This triggers the router to send Queries to neighbors to find a new path.
