It takes too long when Hello packet is lost. Repairing split flooding topology needs to be fast.
Fortunately, lost hello packets are a relatively rare occurrence. While repairing the flooding topology needs to be done expediently, attempting to do so and triggering a cascade failure of the network is counter-productive. Given this alternative, a bit of extra delay when adding a new system to the network, or trying to recover from multiple failures seems wise. Rushing and making things worse does not. The first priority must remain network stability. [Les:] Just to put this minor issue to rest… It would also be possible for the node making the temporary flooding request to send hellos at a faster rate (say once a second rather than once every 10 seconds) until it sees that the neighbor is sending LSP/SNP updates. This just isn’t a significant issue. Les
