Figure 6-3 Traffic Redirect Example
The following network topology allows you to avoid triangle route security issues when the backup
gateway is connected to the LAN. Use IP alias to configure the LAN into two or three logical
networks with the Prestige itself as the gateway for each LAN network. Put the protected LAN in one
subnet (Subnet 1 in the following figure) and the backup gateway in another subnet (Subnet 2).
Configure filters that allow packets from the protected LAN (Subnet 1) to the backup gateway (Subnet
2).
