Example:
Setting the OSPF route cost of interface vlan1 to 3.
Switch(Config-If-Vlan1)#ip ospf cost 3
18.4.2.2.8 ip ospf dead-interval
Command: ip ospf dead-interval
<time >
no ip ospf dead-interval
Function:
Specifies the interval before regarding a neighbor layer 3 switch invalid; the “
no ip ospf
dead-interval
” command restores the default setting.
Parameters:
<
time
>
is the timeout value for a neighbor layer 3 switch to be considered invalid in
seconds; the valid range is 1 to 65535.
Default:
The default timeout value for a neighbor layer 3 switch to be considered invalid is 40
seconds (usually 4 times of the hello-interval).
Command mode:
Interface Mode
Usage Guide:
If no HELLO packet is received from a neighbor layer 3 switch within the
dead-interval
time, that switch is considered unreachable and invalid. This command allows the
user to set default time of a neighbor layer 3 switch to be considered invalid. The
dead-interval
value set will be written to the HELLO packet and send with it. For OSPF protocol to run properly,
the
dead-interval
parameter between the interface and a neighbor layer 3 switch must be the same,
and be at least four times of the
hello-interval
value.
Example:
Setting the OSPF route invalid timeout value of interface vlan1 to 80 seconds..
Switch(Config-If-Vlan1)#ip ospf dead-interval 80
18.4.2.2.9 ospf
enable
area
Command: ip ospf enable area
<area_id>
no ip ospf enable area
Function:
Sets an area for the interface; the “
no ip ospf enable area
” command cancels the setting.
Parameters:
<area_id>
is the area number where the interface resides, ranging from 0 to
4294967295.
Default:
The interface has no area configured by default.
Command mode:
Interface Mode
Usage Guide:
To run OSPF protocol on an interface, an area must be specified for that interface.
Example:
Specifying interface vlan1 to area 1.
Switch(Config-If-Vlan1)#ip ospf enable area 1
18.4.2.2.10 ip ospf hello-interval
Command: ip ospf hello-interval
<time>
no ip ospf hello-interval
Function:
Configures the interval for sending HELLO packets from the interface; the “
no ip ospf
hello-interval
” command restores the default setting.
Parameters:
<
time
>
is the interval for sending HELLO packets in seconds, ranging from 1 to 255.
