Select all that apply.

• A

  The main function is to prevent network attacks based on source address spoofing.

• B

  In strict mode, it does not check whether the interface matches. As long as there is a route to the source address, the message can pass.

• C

  The loose mode not only requires corresponding entries in the forwarding table, but also requires that the interface must match to pass the URPF check.

• D

  Use URPF's loose mode in an environment where routing symmetry cannot be guaranteed.
