At 1:50 are you saying that if the receiving routers are part of the successor path then they’ll forward the query downstream because that route is bad?
Let's say a router receives a query for a route. It can either respond directly, or forward that query out. If this router received this query from the router that it thinks is the successor, then it doesn't have a good response for the query. That means it needs to forward the query to other routers, to see if they have a better path. However, if the router that received the query has a valid path to the destination, it can respond to the original query with this information
