What is rlRaGuardPolicyRouterPrefMax?
This read-write INTEGER (unspecified(-1), disabled(0), low(1), medium(2), high(3)) in the RA Guard policy table sets the maximum advertised router-preference value a Router Advertisement is allowed to carry. An admin cares because pairing it with the minimum lets RA Guard pin the accepted preference to exactly what the legitimate router advertises, catching anything advertising a suspiciously higher preference meant to win a client's default-router race. For example, setting this to medium(2) alongside a minimum of medium(2) on policy "raguard-host" rejects any RA claiming high(3) preference.
