ipv6 ospf
hello-interval
This command specifies the interval between sending hello packets on an
interface. Use the no form to restore the default value.
Syntax
ipv6 ospf hello-interval seconds [instance-id instance-id]
no ipv6 ospf hello-interval [instance-id instance-id]
seconds - Interval at which hello packets are sent from an interface. This
interval must be set to the same value for all routers on the network.
(Range: 1-65535)
instance-id - Identifies a specific OSPFv3 routing process on the link-local
network segment attached to this interface. (Range: 0-255)
Command Mode
Interface Configuration (VLAN)
Default Setting
10 seconds
Command Usage
Hello packets are used to inform other routers that the sending router is still active.
Setting the hello interval to a smaller value can reduce the delay in detecting
topological changes, but will increase routing traffic.
Example
Console(config)#interface vlan 1
Console(config-if)#ipv6 ospf hello-interval 5
Console(config-if)#

no ipv6 ospf priority [instance-id instance-id]
priority - Sets the interface priority for this router. (Range: 0-255)
