Example: Configuring Policing and Marking of Traffic Entering a VPLS Core
This example firewall filter allows a service provider to limit the aggregate broadcast
traffic entering the virtual private LAN service (VPLS) core. The broadcast, unknown
unicast, andnon-IP multicast trafficreceived fromone ofthe serviceprovider’scustomers
on a logical interface has a policer applied. The service provider has also configured a
two-rate, three-color policer to limit the customer’s IP multicast traffic. For more
information onthe configurationofpolicers,see theJunos OSClassofServiceConfiguration
Guide.
The position of the router is shown in Figure 14 on page 96.
Figure 14: Policing and Marking Traffic Entering a VPLS Core
There are four major parts to the configuration:
The policer for broadcast, unknownunicast, and non-IP multicasttraffic.This example
marks the loss priority as high if this type of traffic exceeds 50 Kbps.
The two-rate, three-color policer for IP multicast traffic. This example configures a
committed information rate (CIR) of 4 Mbps, a committed burst size of 256 Kbytes, a
peak information rate of 4.1 Mbps, and a peak burst size of 256 Kbytes (the same as
the CIR).
The filter that applies the two policers to VPLS.
The application of the filter to the customer interface configuration as an input filter.
NOTE: This example does not present exhaustive configuration listings for
all routers in the figures. However, you can use this example with a broader
configuration strategy to complete the MX Series router network Ethernet
Operations, Administration, and Maintenance (OAM) configurations.
