You need to input two valid source IPv4/IPv6 addresses and at least one valid destination IPv4/IPv6 address.
The address scope, label, and preference are automatically computed and displayed. As soon as
two source addresses and at least one destination address are validated, then the best
pair of source and destination is evaluated against
policy (please contact me -- see github -- if you know about other policies).
