5.9.3 POLICY ROUTING
In computer networking, policy-based routing (PBR) is a technique used to make routing decisions
based on policies set by the network administrator.
When the 6401 Rugged Router receives a packet it normally decides where to forward it based on the
destination address in the packet, which is then used to look up an entry in a routing table. However,
in some cases, there may be a need to forward the packet based on other criteria. For example, a
network administrator might want to forward a packet based on the source address, not the destination
address. This should not be confused with source routing.
Policy-based routing may also be based on the size of the packet, the protocol of the payload, or other
information available in a packet header or payload. This permits routing of packets originating from
different sources to different networks even when the destinations are the same and can be useful
when interconnecting several private networks.
Policy Routing Setup
A maximum of 8 policies can be added to the 6401 router.
Enter the policy name, policies, and WAN interface then click "Apply/Save" to add the entry to the
policy routing table.
Note: If selected "IPoE" as WAN interface, default gateway must be configured.
Select the user interface from all the WAN interfaces that have been
configured. For example. pppoa_0_0_38/pppoa0, this will be the
WAN interface out of the Router
