Multiple ATM VPI/VCIs and IP interfaces

Introduction

In case of multiple ATM VPI/VCIs and multiple IP interfaces, the use of labels provides a more flexible means

of determining to which next hop an IP packet has to be forwarded and via which IP interface and ATM VPI/

VCI a packet is sent.

Consider the following practical example. Imagine a DSL connection that is used both for leisure (HTTP, e-

mail, chatting, messaging,...) and professional use (home working or VPN) via two computers. In this

scenario the data that needs to be transferred for professional use has obviously higher priority than the for

example chatting data.

Suppose that the PPP connection "PPPoA_1" is configured for low priority data and PPP connection

"PPPoA_2" is configured for high priority data.

For more information about configuring IP Quality of Service see the "The IPQoS Configuration Guide".
