Note that "metric" is a bit vague term; it has significantly different
implications whether it's applied before or after the
longest-prefix-match.  Ie. whether it is used as a sequential number in
which to look for prefixes in different protocol-specific routing tables
or to compare among different routes of the same prefix and length.

In almost all cases, it's the latter.
