Loose uRPE
Strict uRPF
Default uRPE
Reverse uRPE

Explanation: Strict Unicast Reverse Path Forwarding (uRPF) is a security feature that verifies if a packet is arriving on the interface that the router would use to reach the packet's source IP address according to the Forwarding Information Base (FIB). If the source address and ingress interface do not match, the packet is considered spoofed and is dropped.
