RPF strict
fib lookup of packet source address must return a match
RPF strict with allow default mode
performs strict RPF check if source address lookup returns a regular FIB route, otherwise the default route will be used for strict RPF checking as well
RPF loose
fib lookup of packet source address returns a "match" and the fib lookup result indicates that the source is reachable through at least one "real" interface
RPF loose with allow default mode
performs loose RPF checking if source address lookup returns a regular FIB route, otherwise the default route will be used for loose RPF checking as well.
