Retries
Thissettingspecifiesthenumberofconsecutivesuccessfulping/DNSlookupresponses
thatmustbereceivedbeforethePeplinkBalancetreatsapreviouslydownWANconnection
asupagain.Bydefault,RecoverRetriesissetto3.Usingthedefaultsetting,aWAN
connectionthatistreatedasdownwillbeconsideredasupagainuponreceivingthree


Note
IfaWANconnectiongoesdown,alloftheWANconnectionsnotsetwithaConnectionTypeofAlwaysonwill
alsobebroughtupuntilanyoneofhigherpriorityWANconnectionsisupandfoundtobehealthy.Thisdesigncould
increaseoverallnetworkavailability.
Forexample,ifWAN1,WAN2,andWAN3haveconnectiontypesofAlwayson,BackupPriorityGroup1,and
BackupPriorityGroup2,respectively,whenWAN1goesdown,WAN2andWAN3willtrytoconnect.IfWAN3is
connectedfirst,WAN2willstillbekeptconnecting.IfWAN2isconnected,WAN3willdisconnectorstopconnecting.
