Lists the default DSCP value used in DSCP control traffic and provides guidance on configuration options and considerations for network service providers.
The DSCP control traffic uses the default DSCP value of 48. However, you can change the default value and configure it on the edge devices. All network service providers may not necessarily use DSCP 48.
The BFD packet having the default DSCP can also be used for other features such as PMTU. A change in the default DSCP means that the other features are affected by the new default DSCP value. Therefore, we recommend that you configure the highest priority DSCP marking that the service provider provides (usually 48, but can be different based on the SLA agreement of the service provider). The color level overrides the global level default DSCP marking.
