Other Restrictions
The following limitations apply to routes published by network instances that have established a learning relationship with the same route table:
- Network segments must not overlap. If they do, it is considered a routing conflict. The first route learned by the route table will be marked as "Available" and take effect, while subsequent conflicting routes will be marked as "Conflict" and will not take effect.
