Interface view 

: Designated router (DR) election priority of the interface, in the range of 0 to 255. 

Use the ospf dr-priority command to configure the DR election priority of the interface. 

Use the undo ospf dr-priority command to restore the default. 

By default, the DR election priority of an interface is 1. 

The DR election priority of an interface determines the qualification of the interface. The interface with a 
higher priority will be preferred when an election conflict occurs. An interface with a DR priority of 0 
does not take part in any DR election.  

The priority of a router affects the DR and BDR election. However, a router that has a higher priority 
specified after the DR and BDR have been selected cannot become the DR or BDR immediately. 

# Set the DR election priority of the interface VLAN-interface 10 to 8.
