Figure 4-15: RSR directed to a destination IP address (individual host)
In a business continuity application where the router also has a routable IP
address from a wireline gateway connection (as shown in Figure 4-16) the IT
administrator may prefer to use that lower cost connection for data sourced from
the AirLink gateway, such as SNMP or ALMS data. When reliable static routing is
configured, the Tracking Object tests the validity of the primary route, and data
from the AirLink gateway is transmitted through the primary route (in this
example, the wireline connection). If the tracking object determines that the
primary route is down, data is transmitted through the backup (in this example,
the wireless connection).
