Routes that have a valid successor are said to be in a “passive” state. If, for some reason, a router loses a route through its successor and does not have a feasible successor for that route, then the route transitions to an “active” state. In the active state, a router sends queries out to its neighbors requesting a path to the lost route.

6 i" Y6 z$ N: m8 n3 iWhen an EIGRP neighbor receives a query for a route, it behaves as follows:

If the EIGRP topology table does not currently contain an entry for the route, then the router immediately replies to the query with an unreachable message, stating that there is no path for this route through this neighbor.

7 w$ z2 O0 V  IIf the EIGRP topology table lists the querying router as the successor for this route and a feasible successor exists, then the feasible successor is installed and the router immediately replies to the query.
( t- z, v' s# }; s- _
: _) b; Q- `" D6 K3 rIf the EIGRP topology table lists the querying router as the successor for this route and a feasible successor does not exist, then the router queries all of its EIGRP neighbors except those sent out the same interface as its former successor. The router will not reply to the querying router until it has received a reply to all queries that it originated for this route.

If the query was received from a neighbor that is not the successor for this destination, then the router replies with its successor information.
