From looking at the EIGRP topology table, what is the approach to find out which networks is a given router connected to ?
For example, imagine I want to find out which networks is the router at 188.8.131.52 directly connected to ? What should I consider when looking into that information in the show EIGRP topology table shown below ?
Initially I thought it was by looking at the 'connected' information, but then the answer from the book contradicts this approach. According to the book, the correct answer is that router 184.108.40.206 is directly connected to 3 networks:
Any idea what is the rationale used on this ?

The best way to check which are directly connected networks for the router 18.104.22.168
is to look at the topology table on that router instead.
This table is of a router that is on the same subnet as the one in question.
To confirm this you would see the router ID just after the command is input (its been omitted in this output though).
The 22.214.171.124 router is a successor to a few networks however that only means that it is the next hop or downstream neighbor. If its table does show the 3 networks are directly connected then the statement is true.
But I don't think you could be 100% sure they are directly connected by looking at another routers table.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
