how to diffrentiate between the route and the summary route in the routing table??

[Dr.X]

welcome bro, assume that i am a router R1 and i recived a summary router from my neighbour router R2 , now when i type the command

#sh ip route , i note that the summary is prefix/prefix lenght  now how to diffrentiate this from being summary route or being a subnet/subnetmast ??????

assume that i dont know which one the summary ????????

Why do you need to know the difference? The forwarding code will look in the fib to determine most specific match for the destination IP address regardless of whether downstream peers originated it via a summary statement or "naturally". Do I misunderstand your question?
