EIGRP中的SIA是什么意思？

参考答案: If a route lose on a router and no feasible successor is found for the route，the router will begins a diffusing computation.The router will set the route in active state and send queries to all of its neighbors，and meanwhile the router will set a active timer.If all expected replies are not received before the Active time expires， the route is declared stuck-in-active （SIA）.
The neighbors that did not reply will be removed from the neighbor table， and the diffusing computation will consider the neighbor to have responded with an infinite metric.
