If route optimization is required, you must make the following network programming changes:
On each cluster element, program the route optimization identifier the same as the element's CEID.
On all other network elements, program a second ARS route to reach the cluster. For example:
Node ID + # of internal digits to follow, and
Node ID + # CEID digits + internal digits to follow (new entry)
Note: For more information on these topics, see Route Optimization.
