The SIA-retransmit timer does two things. If neighbors are responding to SIA-queries, large networks are given more time to respond to address queries. If neighbors are not responding, the neighbor is reset. Only the router that is not receiving responses from its neighbor will reset the adjacency. Before the SIA-retransmit timer was introduced, any router that did not receive a response to an active query after the Active timer expired would reset the neighbor adjacency, even if the problem was somewhere downstream in the network.
