The interface priority is a value that you assign to an OSPF router to
determine its status as a designated router. A router can function in one
of three ways:
Designated router (DR) — The router that has the highest priority
value (unless a designated router already exists on the subnetwork)
Backup designated router (BDR) — A router that has a lower
priority value
Not a designated router — A router that has a priority value of 0
The default priority value is 1.
To set the interface priority:
1 From the top level of the Administration Console, enter:
ip ospf interface priority
2 Enter an IP interface.
3 Enter the priority value.
The interface area ID associates the interface that you specify with an
OSPF area. See "Defining Areas" on page 13-2 for more information
about OSPF areas.
CAUTION: Set the area ID to the same value for all routers on the
network segment because they are in the same area.
To associate an interface with an OSPF area:
1 From the top level of the Administration Console, enter:
ip ospf interface areaID
2 Enter an IP interface.
3 Enter the area ID number, in the form of an IP address.
