4. Configure Area 2 as a totally stub area to reduce the stub area routing table size:
# Configure Area 2 as a totally stub area on Router C.
[RouterC-ospfv3-1-area-0.0.0.2] stub no-summary
# Display OSPFv3 routing table information on LB.
[LB] display ospfv3 routing
E1 - Type 1 external route, IA - Inter area route, I - Intra area route
E2 - Type 2 external route, * - Selected route

The output shows that route entries are reduced. All non-direct routes are removed, except the
default route.
Configuring OSPFv3 DR election
Network requirements
• In Figure 203, the priority of LB is 100, the highest priority on the network, so it becomes the DR.
• The priority of Router C is 2, the second highest priority on the network, so it becomes the BDR.
• The priority of Router B is 0, so it cannot become a DR.
• Router A has the default priority 1.
