The set precendence tunnel and set dscp tunnel commands are not supported but general Multicast
VPN is supported, as shown in the following example.
QoS on Multicast VPN: Example
In this example, there are three services offered across the network: mobile, enterprise, and other
services. Mobile traffic is classified as broadband 2G mobile traffic and 3G mobile traffic.
Control traffic needs the highest priority and has priority level 1. Broadband 2G mobile traffic has
priority level 2. A priority queue is associated with each of these traffic classes. Traffic in these classes
is policed at a rate of 100 percent, which means that full line rate bandwidth is dedicated to these traffic
classes.
Remaining bandwidth is distributed across the Mcast_BBTV_Traffic class, Enterprise_Traffic class, and
Enterprise_Low_Traffic class.

QoS on NxDS0 Interfaces
For QoS on NxDS0 interfaces, the shape, police, and queuing minimum rate is 8 kbps and granularity is
1 kbps. When QoS is applied to a low speed NxDS0 link, frame relay fragmentation (frf12) configuration
is also recommended in order to provide low delay for real-time priority traffic. The common
configurations on NxDS0 interfaces are:
• One-level policy applied to a main interface without Frame Relay configured
• Two-level policy applied to a subinterface with Frame Relay configured
