Anelaborationonthetechnicaldetailsoftheimplementationofvirtualrouterredundancyprotocol(VRRP,
RFC3768)bytheBalancefollows:
● InanHAconfiguration,thetwoPeplinkBalanceunitscommunicatewitheachotherusingVRRP
overtheLAN.
● ThetwoPeplinkBalanceunitsbroadcastheartbeatsignalstotheLANatafrequencyofone
heartbeatsignalpersecond. 
● IntheeventthatnoheartbeatsignalfromthemasterPeplinkBalanceunitisreceivedin3
seconds(orlonger)sincethelastheartbeatsignal,theslavePeplinkBalanceunitbecomes
active.
● TheslavePeplinkBalanceunitinitiatestheWANconnectionsandbindstoapreviously
configuredLANIPaddress.
● AtasubsequentpointwhenthemasterPeplinkBalanceunitrecovers,itwillonceagainbecome
active.
