Configure Route Dominance Rules (Location Referencing)

Summary

Configures a set of rules to determine the dominant route in a network where there are concurrent routes.

Usage

• The Order Type parameter's Numeric option supports numbers only, such as 1, 2, 11, 22. The Alphanumeric option supports both numbers and text, such as 1, 2, 11, 22 and 1, 11A, 22A, 22B.

• When multiple fields are configured using the Fields parameter, the field values are concatenated in the order in which the fields have been added. For example, if the RouteType field is added first and has a value of SR and the RouteNumber field is added second and has a value of 18, the resulting concatenated field is SR18.

  For example, if SR18 is a multifield route ID that comprises the RouteType (SR) and RouteNumber (18) fields, select RouteType and RouteNumber for the Fields parameter.

• When the Exceptions parameter is specified, route dominance is determined first by matching exceptions in the order in which they are present in the list, and then by the configured rules. The exception field values are comma-separated.

  For example, if Exceptions values are configured for Route3, Route7, and Route9, these exceptions are considered as dominant routes in their listed order before any configured rules are considered.
