Usage Guide:
If no HELLO data packet received after the
dead-interval
period then this layer 3
switch is considered inaccessible and invalid. This command modifies the dead interval value of
neighboring layer 3 switch according to the actual link state. The set
dead-interval
value is
written into the Hello packet and transmitted. To ensure the normal operation of the OSPF
protocol, the dead-interval between adjacent layer 3 switches should be in accordance or at
least 4 times of the
hello-interval
value. The command can configure on IPv6 tunnel interface,
but it is successful configuration to only configure tunnel carefully.
Example:
Switch#config terminal
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ipv6 ospf dead-interval 80
1.7.3.9 ipv6 ospf display route single-line
Command: [no] ipv6 ospf display route single-line
Function:
show ipv6 ospf route change the display results of show ipv6 ospf route command.
The “
[no] ipv6 ospf display route single-line
” restores to default display mode.
Default:
Not configured
Command Mode:
Global Mode
Usage Guide:
The show ipv6 ospf route command displays the same route in several lines. This
command will strict that one route will be displayed in one line
Example:
Switch#config terminal
Switch(config)#ipv6 ospf display route single-line
1.7.3.10 ipv6 ospf hello-interval
Command: ipv6 ospf hello-interval
<time> [instance-id <id>]
no ipv6 ospf hello-interval [instance-id <id>]
Function:
Specify the hello-interval on the interface; the “
no ipv6 ospf hello-interval
[instance-id <id>]
” restores the default value.
Parameter: <id>
is the interface instance ID, ranging between 0~255, defaulted at 0
<time >
is the length of the adjacent layer 3 switch, in seconds, ranging between 1
～
65535
Default:
Default HELLO packet sending interval 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
