I am trying to wrap my head around SIA. So when a router looses a route, it places that route in an Active State. At this point it sends a Query out to its neighbors for the route it lost. If those neighbors need to query other neighbors, they will hold off replying to the original router until they receive replies from the neighbors they queried.
It makes more sense to me the original router starts the active timer at the time it sends the initial queries. I understand with newer versions of firmware, at the 90 second point, the original router will send a SIA-Query to neighbors it hasn’t received a reply from and if the original router receives SIA-replies from the neighbors it will hold off on resetting the neighbor adjacency. If the neighbor fails to send a SIA-reply, the original router will reset the neighbor adjacency once the timer expires.
Is my thought process correct with the SIA timer or does the original router wait 3 minutes before it sends the SIA-Queries which at this point, the original router will be 4 minutes and 30 seconds into waiting for replies.
Thanks in advance,
