Q: Can the router Forward a Packet through an Interface that receives the packet?

A: Yes. After receiving a packet on an interface, the router searches the routing table for an entry mapped to the destination address, not the source address. If there is a matched entry, the packet is forwarded even though the inbound and outbound interfaces are the same. Even if URPF is strictly configured, the source address of a packet can still pass the URPF check if it is legal. A packet, therefore, can be forwarded through an interface that receives the packet.
