36.19 ipv6 ospf hello-interval
Command:
ipv6 ospf hello-interval [instance-id
no ipv6 ospf hello-interval [instance-id
Function:
Specify the hello-interval on the interface; the “no ipv6 ospf hello-interval [instance-id
restores the default value.
Parameter:
<id> is the interface instance ID, ranging between 0~255, defaulted at 0
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 Configuration 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. 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 hello-interval 20
