Qos - Policing SUPPORT for GRE Tunnels
The Qos - Policing Support for GRE Tunnels feature allows you to set the Differentiated Services Code
Point (DSCP) and IP precedence values on Generic Routing Encapsulation (GRE) tunnel packets.
Point (DSCP) and IP precedence values on Generic Routing Encapsulation (GRE) tunnel packets.
This feature is essential for MPLS carriers to offer QoS on Multicast VPN services. MVPN uses GRE
tunnels between PE devices, and multicast packets are placed in GRE tunnels for transmission across the
MPLS core network. The Qos - policing SUPPORT for GRE Tunnels feature allows users to configure
QoS for the GRE tunnel packets. Once the GRE packets accurately reflect the QoS markings of the
underlying multicast packets, they may be queued accordingly as they travel across the core nodes.
