Lowest configuration required to apply QoS in a LAN/WAN/WAN2 architecture

For this section, it is assumed that the user already has the lowest configuration required to apply QoS in a LAN/WAN architecture. This section also explains how to add the components needed in order to apply QoS to traffic flowing to the second WAN2 access link (bandwidth in this example: 100 Mbit/s).

QoS-enabled traffic balanced between two WAN access links is fully compatible with all the following routing methods:

• Static routing,
• Dynamic routing,
• PBR (policy-based routing),
• Use of router objects, with or without load balancing.
