Configuring Policy-Based Routing
Policy-based routing (PBR) enhances/modifies existing features in the EdgeSwitch software. These features
are route maps and access-control lists. Route maps are part of routing (see
“Router” on page 200
) and
access control lists are part of QOS (see
“Configuring Access Control Lists” on page 230
). As policy-based
routing feature utilizes services of both features mentioned above, the EdgeSwitch software with a
combination of Routing and QOS packages is required to have PBR functional.
Normally, routers take forwarding decision based on routing tables in order to forward packets to destination
addresses. Policy-Based Routing is a feature that enables network administrator to define forwarding
behavior based on packet contents. In brief, Policy-Based Routing overrides traditional destination-based
routing behavior.
The EdgeSwitch software’s policy-based routing feature match the following packet entities and overrides
traditional forwarding behavior accomplished through destination-based routing:
• The size of the packet
• Protocol of the payload
• Source MAC address
• Destination MAC address
• Source IP address
• Destination IP address
• VLAN tag
• Priority
