This scenario requires three probes:
Ping monitors connectivity to the Internet.
HTTPPrimary informs the Web server when the router is using the
primary link.
HTTPBackup informs the Web server when the router is using the
backup link.
This scenario requires one track to monitor the state of the RemotePing probe
and control the primary static route. The HTTP probes do not require a track.
This scenario requires three PBR route map entries:
Probes 10 routes RemotePing probe traffic out the primary interface.
Probes 20 routes HTTPPrimary probe traffic out the primary interface.
Probes 30 routes HTTPBackup probe traffic out the backup interface.
(Remember to add the probe traffic to the interesting traffic for demand
routing. See "Matching the Interesting Traffic" on page 3-24 in Chapter 3:
Configuring Backup WAN Connections.)
Follow these steps to configure your router:
1. Create the probes. The HTTPPrimary and HTTPBackup probes must use
different source ports so that PBR can distinguish their traffic. The raw
strings for the HTTP probes configure them to submit necessary informa-
tion to the remote Web server.
