Explanation:
First, we should notice about the entry in the orange box, it shows that the network
172.17.10.0/24 is directly connected with this router and has a FD of 28160. So we can
guess the networks that directly connected with router at 172.17.10.2 will be shown with an
AD of 28160. From that, we find out 3 networks which are directly connected to the router at
172.17.10.2 (they are green underlined). The network 172.17.10.0/24 is surely directly
connected to the router at 172.17.10.2 (in fact it is the network that links the router at
172.17.10.2 with Core1 router).
