Configuration Task

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.

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.
