Use this command to enter an exception route entry. An exception route is associated with an entry in the Routing table. When the Origin-Based MTP Routing feature is enabled and turned on, the least cost route available for an MSU to be routed to a Destination Point Code over a specified linkset is used.
Up to 6 routes can be defined to a single entry in the Routing table. Up to 8000 routesets can be defined for an STP. This total must include at least one normal route (not an exception route). The remaining 7999 routesets can include any combination of normal and exception routes.
Note:
A routeset is a collection of routes to a destination. Each routeset can have up to 6 routes, with 16 links on each route. An exception routeset is a collection of up to 6 exception routes that have the same DPC, exception class, and criteria.Parameters

Dependencies
Only one of the opc, ilsn, cic, or si parameters can be specified for a exception route entry.
For an ANSI origination point code that is defined using asterisks (nnn-*-*), the value of the network identifier subfield (nnn) must be greater than 5.
If the ecic parameter is specified, the cic parameter must also be specified.
The ecic parameter value cannot be less than the cic parameter value.
The opc/opca/opci/opcn/opcn24/opcn16 parameter value cannot be the same as the dpc parameter value.
The Origin-Based MTP Routing feature must be enabled and turned on before this command can be entered.
The point code specified by the dpc/dpca/dpci/dpcn/dpcn24/dpcn16 parameter must already exist in the Route table.

The linkset name, as defined by the ilsn or lsn parameter, must exist.
An exception route entry cannot already exist with the same input parameter values, other than the relative cost.

A maximum of 6 exception routes can be associated with the specified DPC and criteria.
A maximum total of 8000 exception routes and normal routes can be defined for the EAGLE. At least one route must be a normal (not exception) route. The remaining routes (up to 7999) can be all normal routes, all exception routes, or any combination of normal and exception routes.
The network domain of the adjacent point code in the linkset or of the routes in the specified routeset must be the same as the network domain of the specified destination point code or its alias.
The adjacent or secondary point code type and group code of the linkset or linksets in the specified routeset must match the point code type and group code of the destination point code.
The specified CIC/ECIC range must not overlap an existing range.
The Linkset table is corrupt or cannot be found.

If the ilsn and lsn parameters have the same value, or if the value specified for the opc/opca/opci/opcn/opcn24/opcn16 parameter is the same as the APC of the linkset specified by the lsn parameter, then the force=yes parameter must be specified.
The opcn parameter must be in the same ITU-N group as the dpcn parameter.
