Maintaining OSPFv3 Neighbor Relationship

Setting an Interval for Sending Hello Packets

By adjusting the Hello interval set on OSPFv3 neighbors, you can change the speed of establishing the neighbor relationship, therefore changing the speed of network convergence.

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.

Setting an Interval for Retransmitting LSAs to Neighboring Routers

After a router sends an LSA to its neighbor, the router expects to receive an LSAck packet from its neighbor. If the router does not receive an LSAck packet within the LSA retransmission interval, it retransmits the LSA to the neighbor.

Setting a Delay for Transmitting LSAs on the Interface

It takes time to transmit OSPFv3 packets on a link. Therefore, a certain delay is added to the aging time of an LSA before the LSA is sent.
