What can stub area design improve?
- LSDB size on routers in the backbone
- the ability to reach outside networks
- the number of adjacencies in the stub
- CPU utilization on routers in the stub
Explanation: Stub area design is intended to reduce the size of the LSDB and routing tables within that specific area by blocking external LSAs and replacing them with a default route. This reduction in data processing directly results in improved CPU and memory utilization for the routers located inside the stub area.
