Authentication
OSPFprotocolexchangescanbeauthenticatedsothatonlytrustedroutingdevices
canparticipate.Thisensureslessprocessingonroutingdevicesthatarenot
listeningtoOSPFpackets.
OSPFallowspacketauthenticationandusesIPmulticastwhensendingand
receivingpackets.Routersparticipateinroutingdomainsbasedonpre‐defined

EnterpriseNOSsupportssimplepassword(type1plaintext

allowsapasswordtobeconfiguredperarea.
