interface or virtual interface template, use the following interface configuration
commands:
Step 1
Step 2
Step 3
Step 4
Note
You can use the ip rtp reserve command instead of configuring RSVP. If you

Task
Enable Multilink PPP.
Enable real-time packet
interleaving.
Optionally, configure a
maximum fragment delay of
up to 20 milliseconds.
Reserve a special queue for
real-time packet flows to
specified destination User
Datagram Protocol (UDP)
ports, allowing real-time
traffic to have higher priority
than other flows. This
applies only if you have not
configured RSVP.
