- | Overlapping prefix delegation pools in different subnets | Yes | Can act as a substitute for a global pool mechanic. When assigning leases from |
- | | | one pool, Kea correctly excludes leases given under any pool that overlaps |
- | | | with it such that no lease is given twice. |
+ | Overlapping prefix delegation pools in different subnets | Yes | Specifying the same prefix delegation pool in different subnets can be used as an |
+ | | | equivalent of the global pool. In that case, the server can delegate the same |
+ | | | prefixes regardless of the client's subnet. If a prefix from such a pool is |
+ | | | delegated to a client in one subnet, the same prefix will be renewed for this |
+ | | | client if it moves to another subnet. Another client in a different subnet will |
+ | | | not be delegated a prefix already delegated to the client in any of the subnets. |

| Prefix delegation pools not matching the subnet prefix | Yes | It is common in many deployments to configure the prefix delegation pools not |
| | | matching the subnet prefix, e.g. a prefix pool of 3000::/96 within the |
