92 CHAPTER 8: SETTING IP PARAMETERS
Setting the Mode You can set the OSPF mode for each interface. The mode can be enabled
or disabled. You must set the mode to enabled to run OSPF routing.
The default mode is disabled.
To set the mode for the interface:
1 Enter the following at the top-level menu:
ip ospf interface mode
The following prompt is displayed:
Select IP interfaces (1-3|all) [1]:
2 Select the index number(s) representing the interface(s).
Enter OSPF mode {disabled,enabled} [enabled]:
3 Enable or disable the OSPF mode for each interface as required.
Setting the Priority 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 with the highest priority value
is always the designated router, unless a designated router already
exists on the subnetwork.
■ Backup designated router (BDR) — A router with a lower priority
value.
■ Not a designated router — A router with a priority value of 0.
