R0106-HP MSR Router Series ACL and QoS Configuration Guide(V7)

Red packets : 0 (Packets) 0 (Bytes)

QPPB configuration example in an MPLS L3VPN

Network requirements

As shown in Figure 23, all routers run BGP.

Configure QPPB so that Router C can perform the following tasks:

• Receive routes.

• Set the QPPB local QoS IDs.

• Use the QoS policy to limit the traffic rate to 2 Mbps in each direction.

Configuration procedure

1. Configure IP addresses for each interface. (Details not shown.)

2. Configure a BGP connection on Router A.

<RouterA> system-view

[RouterA] bgp 100

[RouterA-bgp] peer 167.1.1.2 as-number 200

[RouterA-bgp] peer 167.1.1.2 connect-interface gigabitethernet 2/1/1

[RouterA-bgp] address-family ipv4

[RouterA-bgp-ipv4] import-route direct

[RouterA-bgp-ipv4] peer 167.1.1.2 enable

[RouterA-bgp-ipv4] quit

[RouterA-bgp] quit

3. Configure Router B:

# Configure a VPN instance.

<RouterB> system-view

[RouterB] ip vpn-instance vpn1

[RouterB-vpn-instance-vpn1] route-distinguisher 200:1

[RouterB-vpn-instance-vpn1] vpn-target 200:1 export-extcommunity
