Configuring Basic OSPFv3 Functions
Data Preparation
To establish or maintain the OSPFv3 neighbor relationship, you need the following data.
No.
Data
1
Interval for sending Hello packets
2
Dead time of the neighbor relationship
3
Interval for retransmitting LSAs to adjacent routers
4
Delay in sending LSAs
5.4.2 Configuring the Interval for Sending Hello Packets
By adjusting the Hello interval set on OSPFv3 neighbors, you can change the speed of
establishing the neighbor relationship, thus changing the speed of network convergence.
Context
Hello packets are periodically sent to the neighbor switch to detect and maintain the neighbor
relationship and to elect the DR and the BDR. RFC 2328 requires that the Hello timer values of
neighbors be consistent. The value of the Hello timer is inversely proportional to the route
convergence speed and network load.
Do as follows on the switch that runs OSPFv3.
Procedure
Step 1
Run:
system-view
The system view is displayed.
Step 2
Run:
interface
vlanif
interface-number
The interface view is displayed.
Step 3
Run:
ospfv3 timer hello
interval
[
instance
instance-id
]
The interval for sending Hello packets is set on the interface.

5.4.3 Configuring Dead Time of Neighbor Relationship
If a router does not receive a Hello packet from its neighbor within the Holddown time, the router
considers the neighbor relationship invalid.
