Link-Specific WAN QoS Recommendations
This section contains configuration recommendations for WAN QoS on a variety of high-speed (over
768 kbps) and slow-speed (768 kbps and less) links. It includes the recommendations for the following:

High-Speed Point-to-Point Links
High-speed point-to-point links can be configured as MLP links, PPP links, or HDLC links. An
advantage of MLP is that future expansion is easier to manage as there are fewer configuration changes
required if an additional link to a remote site is added.
Note
cRTP can be used on high-speed point-to-point links, but do so with caution. CPU performance should
first be evaluated when enabling cRTP on high-speed links.
For more information on cRTP, see

illustrates how MQC policies can be applied to a high-speed MLP link.
Example 4-3
High-Speed MLP Link
interface Multilink40
description MLP Link to BRANCH#40
bandwidth 1536
ip address 10.200.40.1 255.255.255.252
service-policy output WAN-EDGE
This command applies the MQC policy to the interface.
