Answer: Pending
Explanation:
Unicast Reverse Path Forwarding
Unicast Reverse Path Forwarding (uRPF) can mitigate spoofed IP packets. When this feature
is enabled on an interface, as packets enter that interface the router spends an extra moment
considering the source address of the packet. It then considers its own routing table, and if
the routing table does not agree that the interface that just received this packet is also the
best egress interface to use for forwarding to the source address of the packet, it then denies
the packet.
