Chapter 50 OSPF
XGS4600 Series User’s Guide
450
Routers B and C do not have a direct connection with each other. Therefore they should not be allowed
to become DR or BDR. Only router A should become the DR.
Figure 357 OSPF Router Election Example
You can assign a priority to an interface which determines whether this router will be elected to be a DR
or BDR. The router with the highest priority becomes the DR, while a router with a priority of 0 does not
participate in router elections. In Figure 357 on page 450 you can assign a priority of 0 to routers B and C,
thereby ensuring they do not become DR or BDR and assign a priority of 1 to router A to make sure that
it does become the DR.
