You can also set up VRRP using two AirLink gateways —one configured as the
VRRP Master and the other as the VRRP Backup. The Backup AirLink gateway
provides an alternate route when the Master AirLink gateway loses coverage.
For example, if you have cellular accounts with two different Mobile Network
Operators (MNOs) you might prefer to use MNO A's connection, but to maintain
continuity, you would like traffic to switch to MNO B if A's network is down and
switch back to A's network once the connection is re-established.
