EIGRP : no periodic updates .
EIGRP : if link speed > T1 ( Hello interval = 5 sec & Dead interval = 15 sec)
EIGRP : if link speed ----------------------------------------------------------
OSPF : no periodic updates . periodic hello are sent every 10 seconds . Dead interval=10 sec * 4 periodic hello =40 sec
OSPF : periodic LSDB ( link state database ) are sent every 30 mins.
