9.3 Policy Routing
Traditionally, routing is based on the destination address only and the GPON Device takes the
shortest path to forward a packet. Policy routing allows the GPON Device to override the default
routing behavior and alter the packet routing 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 routing to direct traffic from different users through different
connections or distribute traffic among multiple paths for load sharing.
Use the Policy Routing screen to view and configure routing policies on the GPON Device. Click
Advanced Setup > Routing > Policy Routing to open the following screen.

LABEL DESCRIPTION
IP Version Select whether your IP type is IPv4 or IPv6.
Destination IP address/
prefix length
Enter the IPv4 or IPv6 address and network length of the final destination.
Interface Select the interface through which this static route sends traffic.
Gateway IP Address Enter the IP address of the gateway when you configure a static route that uses
an IP-based interface (such as IPoE, IPoA, or LAN). The gateway is a router or
switch on the same network segment as the device's LAN or WAN port. The
gateway helps forward packets to their destinations.
