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.
