Configuring ATM Scheduler Support for Ethernet VPLS over ATM Bridged Interfaces
You can configure ATM scheduler maps on Ethernet VPLS over bridged ATM interfaces.
Before you begin, you must have done the following tasks:
Properly configured the router basics
Verified you have support for VPLS and routing instance configuration
Installed ATM II IQ PICs
When you configure ATM scheduler maps on Ethernet VPLS over bridged ATM interfaces, you can assign ATM traffic to various forwarding classes and queues. This feature is only available with the ATM II IQ PIC with Ethernet VPLS-over-ATM encapsulation.
The configuration takes place in four steps: define the scheduler map for ATM options on the interface, set the encapsulation type to Ethernet VPLS over ATM LLC, attach the scheduler map to the logical interface (unit), and include the interface in the VPLS routing instance configuration.
To configure ATM scheduler maps on Ethernet VPLS over bridged ATM interfaces:
When you are done, the configuration statements you added should look like the listings below.
The scheduler map for ATM options on the interface:
[edit interfaces at-fpc/pic/port atm-options] pic-type atm2; vpi vpi-number; scheduler-maps { scheduler-map-name { forwarding-class forwarding-class-name { (forwarding-class option statements); } } }
The encapsulation type to Ethernet VPLS over ATM LLC:
[edit interfaces at-fpc/pic/port unit unit-number] encapsulation ether-vpls-over-atm-llc; vci vci-number;
The scheduler map to the logical interface (unit):
[edit interfaces at-fpc/pic/port unit unit-number] atm-scheduler-map scheduler-map-name;
The interface in the VPLS routing instance configuration:
[edit routing-instances routing-instance-name] interface at-fpc/pic/port.unit-number; route-distinguisher value; vrf-target target-value; protocols { vpls { site-range value; site site-name { site-identifier number; } } }
