Import Policies At A Glance - 3Com 4007 Implementation Manual

For routes that are accepted into the routing table as defined by the
policy, you can define a new cost metric value for the route, or you
can adjust the existing cost metric using one of these operators:
+ adds the specified number to the existing cost metric
- subtracts the specified number from the existing cost metric
* multiplies the specified number by the existing cost metric
/ divides the existing cost metric by the specified number
% modulo divides the existing cost metric by the specified number
and returns the remainder
The routes are then accepted into the routing table with the cost
metric that has been defined by the import policy.
In case multiple policies match the same route, you can also assign an
administrative weight to define an order of precedence.
