This is a part of the CEF output . How is the attached entry different from last entry where Prefix and Nexthop are equal ?
1. Does not the last entry indicate its a connected/attached route ?
2. Also for the receive entries means those packets are meant for the router ? if they are meant for the router , how does the router determine what needs to be done with this packet. Can you give a example.
please note I do not have any configuration of the router.

Hi Jiten,
1. The last entry indicates a cached adjacency, which means that arp has been resolved for this specific host route.
2. Correct. "Receive" means that these host routes belong to the local router. Packets received with these addresses as destination will be locally processed.

Thanks Harold. so that means for question 1 - So can that indicate its a connected route ? Just curiuos to know why this entry is here.

Hi Jiten,
Yes, it is a connected route for a neighbor for which the arp has already been processed and cached. It is there so that we do not need to go through that same processed as long as the entry is valid.
