What is rlDhcpGuardPolicyPrefMax?
This read-write value sets the maximum acceptable DHCPv6 server preference value that this guard policy validates, where -1 means unspecified and -2 disables the check. An admin uses it to catch servers advertising suspiciously high preference values that could be trying to win over legitimate DHCPv6 servers. For example, setting this to 200 flags any server whose advertised preference exceeds that ceiling as invalid under this policy.
