QPPB configuration example in an IPv6 network
Network requirements
As shown in Figure 26 , all routers run BGP. Device B receives routes, sets the QPPB IP precedence, and
uses the QoS policy to limit the traffic from Device B to Device A to 512 kbps.

Configuration procedure
1. Enable IPv6 globally, and configure IP addresses for each interface (omitted)
2. Configure Device A
# Configure BGP.
system-view
[DeviceA] bgp 1000
[DeviceA-bgp] ipv6-family
[DeviceA-bgp-af-ipv6] peer 168::2 as-number 2000
[DeviceA-bgp-af-ipv6] network 1:: 64
[DeviceA-bgp-af-ipv6] quit
[DeviceA-bgp] quit
3. Configure Device B
# Configure BGP.
system-view
[DeviceB] bgp 2000
[DeviceB-bgp] ipv6-family

[DeviceB-bgp] quit
# Configure a routing policy.
[DeviceB] route-policy qppb permit node 0
