Description If a router running OSPF transmits a "link state advertisement"(LSA) to the peer, it
needs to wait for the acknowledgement packet from the peer. If no
acknowledgement is received from the peer within the LSA retransmission, this LSA
will be re-transmitted. According to RFC2328, the LSA retransmission between
adjacent routers should not be set too short. Otherwise, unexpected retransmission
will be caused.
