In the diagram, the WAN ports of each Pepwave router connect to the router and to the modem.
Both Pepwave routers connect to the same LAN switch via a LAN port.
An elaboration on the technical details of the implementation of the virtual router redundancy
protocol (VRRP, RFC 3768) by Pepwave routers follows:
● In an HA configuration, the two Pepwave routers communicate with each other using
VRRP over the LAN.
● The two Pepwave routers 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 Pepwave router is received in 3
seconds (or longer) since the last heartbeat signal, the slave Pepwave router becomes
active.
● The slave Pepwave router initiates the WAN connections and binds to a previously
configured LAN IP address.
● At a subsequent point when the master Pepwave router recovers, it will once again
become active.
