OSPFv3 packet timer
Hello packets are sent periodically between neighboring routers for finding and
maintaining neighbor relationships, or for DR/BDR election. The hello interval must
be identical on neighboring interfaces. The smaller the hello interval, the faster the
network convergence speed and the bigger the network load.
If a router receives no hello packet from a neighbor after a period, it will declare
the peer is down. The period is called dead interval.
After sending an LSA to its adjacency, a router waits for an acknowledgment from
the adjacency. If no response is received after retransmission interval elapses, the
router will send again the LSA. The retransmission interval must be longer than the
round-trip time of the LSA in between.
LSA delay time
Each LSA has an age in the local LSDB (incremented by 1 per second), but an LSA
is not aged on transmission. You need to add an LSA delay time into the age time
before transmission, which is important for low speed networks.
SPF timer
Whenever LSDB changes, SPF recalculation happens. If recalculations become so
frequent, a large amount of resources will be occupied, reducing operation
efficiency of routers. You can adjust SPF calculation interval and delay time to
protect networks from being overloaded due to frequent changes.
