The output shows that the DR is still Router D.
4. Enable DR/BDR election:
# Perform the shutdown and undo shutdown commands on each interface to enable a new DR/BD
election. (Details not shown.)
# Display neighbors on Router A. The output shows that Router C becomes the BDR.

OSPFv3 route redistribution configuration example
Network requirements
As shown in Figure 97:
• Router A, Router B, and Router C are in Area 2.
• OSPFv3 process 1 and OSPFv3 process 2 run on Router B. Router B communicates with Router A
and Router C through OSPFv3 process 1 and OSPFv3 process 2.
• Configure OSPFv3 process 2 to redistribute direct routes and the routes from OSPFv3 process 1 on
Router B, and set the default metric for redistributed routes to 3. Router C can then learn the routes
destined for 1::0/64 and 2::0/64, and Router A cannot learn the routes destined for 3::0/64 or
4::0/64.
