6.3.2 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, therefore changing the speed of network convergence.
Context
Hello packets are periodically sent to the neighbor router 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.
Issue 02 (2014-09-30)
Adjust the convergence speed of the OSPFv3 network and network load posed by protocol
packets by modifying OSPFv3 timers.
Enable OSPFv3 to be disconnected from its neighbor when the number of OSPFv3 packet
retransmissions exceeds the threshold by configuring Retransmission Limitation for
OSPFv3. This prevents non-stop packet retransmissions if the neighbor does not receive
packets.
Speed up the convergence of an OSPFv3 network by adjusting the intervals for updating
and receiving LSAs.
