which of the following descriptions about urpf loose mode is correct?
A.
It is typically used on point-to-point interfaces where the same interface isused for both
directiongs of packet flows; if the source address has a return route in the FIB table,it is then
checked against the adjacency table to ensure the same interface receiving the packet is the
same interface used for the return path
B.
If a packet fails the uRPF loose mode check, the packet is then transmitted and creates a log
message
C.
It is typically used on multipoint interfaces or on routers where asymmetrical routing is
used(packets are received on one interface but the return path is not on the same interface);loose
mode verifies a source address by looking in forwarding information base(FIB). Created by routing
protocols, to verify there is a return route to the source and to venrify that the path uses a valid
interface
D.
None of above
E.
If a packet fails the uRPF loose mode check ,the packet is then dropped
