The show ip eigrp topology command output on a router displays a successor route and a feasible successor route to network 192.168.1.0/24. In order to improve network convergence, what does EIGRP do when the primary route to this network fails?

  • The router sends query packets to all EIGRP neighbors for a better route to network 192.168.1.0/24.
  • DUAL immediately recomputes the algorithm to calculate the next backup route.
  • Packets that are destined for network 192.168.1.0/24 are sent out the default gateway instead.
  • The backup route to network 192.168.1.0/24 is installed in the routing table.

Explanation: When EIGRP detects that it has lost a successor for a path, the feasible successor instantly becomes the successor route, providing a backup route. This route is installed in the routing table and the router sends out an update packet for that path because of the new EIGRP path metrics.
