Example for Configuring Policy Routing

7.4.1 Network Requirements

The network administrator has a router with 3 computers (192.168.0.2-192.168.0.4)
connected to the LAN side, all computers are routed to internet by WAN1 port and WAN2
port, the requirements are as follows:
 WAN2 link is used to backup WAN1 link to keep an always on-line network.
 The two computers with IP addresses 192.168.0.2 and 192.168.0.3 are required to use
WAN1 for web surfing, WAN2 for other internet activities.

7.4.2 Configuration Scheme

To meet the first requirement, configure link backup on the router. To meet the second
requirement, configure policy routing rules for two computers which use 192.168.0.2 and
192.168.0.3. Note that link backup rule has a higher priority than policy routing rule.
