Figure 12: Failover VPN topology using object tracking
This typical application illustrates the use of object tracking as a backup mechanism for PPPoE
configured on the WAN FastEthernet interface. A track list monitors the state of the connection.
If the WAN FastEthernet interface is down, another connection is used.
In this application, the Branch Gateway is connected to an xDSL modem through PPPoE
encapsulation configured on interface WAN FastEthernet 10/2. The Branch Gateway is
connected to the Internet through the xDSL modem.
Note:
When using a broadband modem (either xDSL or cable), it is recommended to run the VPN
application.
