Cancel Click this to exit this screen without saving any changes. 9.4 Policy Route Traditionally, routing is based on the destination address only and the VMG takes the shortest path to forward a packet. Policy route allows the VMG to override the default routing behavior and alter the packet forwarding based on the policy defined by the network administrator. Policy-based routing is applied to outgoing packets, prior to the normal routing. You can use source-based policy forwarding to direct traffic from different users through different connections or distribute traffic among multiple paths for load sharing. The Policy Route screen let you view and configure routing policies on the VMG. Click Network Setting > Routing > Policy Route to open the following screen.
