Example:
Switch#config terminal
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ip ospf dead-interval 80
13.6.3.21 ip ospf disable all
Command: [no]ip ospf disable all
Function:
Stop OSPF group process on the interface
Command Mode:
Interface Mode
Usage Guide:
This command resets the network area command and stops group
process on specific interface.
Example:
Switch#config terminal
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ip ospf disable all
13.6.3.22 ip ospf hello-interval
Command: ip ospf [<ip-address>] hello-interval
<time>
no ip ospf [<ip-address>] hello-interval
Function:
Specify the hello-interval on the interface; the “
no ip ospf [<ip-address>]
hello-interval
” restores the default value
Parameter: <ip-address>
is the interface IP address shown in dotted decimal notation;
<time>
is the interval sending HELLO packet, shown in seconds and ranging between
1
～
65535
Default:
The hello-interval on the interface is 10 seconds
Command Mode:
Interface Mode
Usage Guide:
HELLO data packet is the most common packet which is periodically sent
to adjacent layer 3 switch to discover and maintain adjacent relationship, elect DR and
BDR. The user set
hello-interval
value will be written into the HELLO packet and
transmitted. The less the
hello-interval
value is, the sooner the network topological
structure is discovered as well larger the cost. The ensure the normal operation of OSPF
protocol the
hello-interval
parameter between the layer 3 switches adjacent to the
interface must be in accordance.
Example:
Switch#config terminal
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ip ospf hello-interval 20
