Figure 7-3 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).
